Why There Is No Random Guess Line Appeared In The Lift Chart?
May 3, 2007
Hi, all here,
Why the lift chart for my mining models evaluation does not have a random guess model line there? As normal, there should be lines like trained models, ideal model, and random guess model? Why is that? What did I miss? Could any experts here shed me any light on that.
Thanks a lot in advance for your advices and help and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,

Is there a Lift chart viewer like the model viewers that can be embedded within your windows apps ? If not, then can this be easily created via Adomd.net api calls ? Has anyone done this easily in custom DM applications ?
Thanks in advance,

Hi,
I tried to create a lift chart with my custom plugin-algorithmn. The chart seems to be correct, but before it is drawn, an error occours:
Function ... Row 1 ... Column 43 ... cannot be used in this context.
(I've translated the key facts of this error message from german)
What did I do wrong?
Best wishes,

Hi,
I am having trouble really understanding what makes a model accurate and effective at predicting some attribute. I can't seem to find any clear documentation about the mining legend of the lift chart on the Mining Accuracy Chart tab when working with the Data Mining Structure designer in VS 2005. Specifically, I would like to know more about what numbers in the Score, Population Correct and Predict Probability columns mean, and why they change when you move the vertical gray bar on the Lift Chart. Also, what is generally a good score to be aiming for, provided that it is highly difficult to get 100% accuracy with the kind of data that I am using.
Any more information on this subject is much appreciated. Thank you for your time,
Chris Burns

Hello--
We're running into an issue where analysts are having problems obtaining lift charts (via the Mining Accuracy Chart UI available in the Visual Studio Analysis Services project) and performing prediction (via the Mining Model Prediction UI).
The issue seems to be related to the underlying analyst security model. Note that this post is related to:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=924641&SiteID=1
Analysts that work on the same problem will only have access to:
- A sandbox relational database (which contains views into the same source database). The analyst is db_owner of the sandbox database, so she/he can create data transformations required, etc. The sandbox database contains views to the source database, but the analyst only has read-access to the specific data elements needed from the source DB. So, they are very restricted w.r.t. the source database, but are db_owners of their sandbox relational databases. Note that the analyst will connect to he database via Windows Authentication.
- An Analysis Services sandbox database to use for their modeling, etc. In this AS sandbox db, we've created a role called "Administrator" and checked the permissions: Full control (Administrator), Process database, and Read definition. The analyst's windows account is the "user" associated with this role.
Also, in this situation, the SQL Server 2005 Relational Engine and Analysis Services are running on a single machine. The goal of this security model is to provide analysts with the ability to work in their "workspaces" (both SQL and AS), but not to see other analysts work, etc.
Under this model, Analysts are able to deploy mining models when the Data Source object that points to their relational "sandbox" DB is set-up with "Impersonation Information" = "Use a specific user name and password", where the Analyst provides their domain account information.
But, when trying to build a lift chart using the same data source view objects that were used to successfully train the model, the following error is occurring consistently:
Window Title: "Loading Mining Accuracy Chart"
Window Text: "Failed to execute the query due to the following error: Execution of the managed stored rocedure GenerateLiftTableUsingDatasource failed with the following error: Exception has been thrown by the target of invocation. Either '<domain><login>' user does not have permission to access the '' object, or the object does not exist. Errors in the high-level relational engine. A connection could not be made to the data source specified in the query. Errors in the high-level relational engine. A connection could not be made to the data source specified in the query.."
Since the Analyst was able to build the model with her/his given '<domain><login>' credentials, it is puzzling why the lift chart is failing.
Thanks in advance for your help,
- Paul

Hello . Because of my graduation project , I interested in data mining application , Adventureworks DW on MS VS 2005 . I opened File->Open->project/solution ->Enterprise -> AdventureworksDW .then I successfully deployed the algorithms decision tree and Clustering . Then I opened tab Mining Accuracy Chart then selected input table "testing" , which I had created before , from vTargetMail . After that , mining structure table and target mail table has automaticaly linked each other .Next , I selected predictive input as 1 , of the predictable row "BikeBuyer" . But , when I clicked "Lift Chart ", I only got a 45 degree line , everytime .. How can I fix it ?

Greetings,
I have a mining structure that I am using to perform a text-mining
classification task. The mining structure contains three models: a
decision tree, a naive bayes and a neural network.
Both the decision tree and the naive bayes models process without
any problems, but I am having significant difficulties with the neural
network model.
Initially when I processed the model, processing would fail altogether with the following error message:
"Memory error: Allocation failure : Not enough storage is available to process this command"
This was remedied by taking the steps prescribed in
http://support.microsoft.com/kb/917885 (I upgraded to SQL 2005 SP1 and
applied all available hotfixes listed in
http://support.microsoft.com/kb/918222/). This got me to the point
where the model (seemingly) processed correctly after restricting the
MAXIMUM_INPUT_ATTRIBUTES to a relatively low number. So after
processing, I went to try and browse the neural network model and view
the lift chart...
<error>
"Execution of the managed stored procedure GetAttributeScores
failed with the following error: Exception has been thrown by the
target of an invocation.Input string was not in a correct format.."
</error>
(see http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=935340&SiteID=17)
Also when I would attempt to view the lift chart and the
classification matrix the queries would time out with the following
error message:
<error>
XML for Analysis parser: The XML for Analysis request timed out before it was completed.
Execution of the managed stored procedure
GenerateLiftTableUsingDatasource failed with the following error:
Exception has been thrown by the target of an
invocation.Microsoft::AnalysisServices::AdomdServer::AdomdException.
</error>
Now, my poking around on Technet lead me to believe that this issue
could finally be resolved by uprading to the CTP release of SQL server
2005 SP2. Now I am still encountering problems. When I go to browse the
model in the Neural Network Viewer, I see the correct drop down menus
to select attributes and attribute values in the "Input" and "Output"
panes but I see no data displayed in the "Variables" pane at the
bottom.
Interestingly, while I cannot view the model contents in the
graphical viewer, the mining model contents viewer reveals model
contents that look to be pretty normal for a trained neural network.
Attempts to view the lift chart time out with the error message:
<error>
XML for Analysis parser: The XML for Analysis request timed out before it was completed.
Execution of the managed stored procedure
GenerateLiftTableUsingDatasource failed with the following error:
Exception has been thrown by the target of an
invocation.Microsoft::AnalysisServices::AdomdServer::AdomdException.
</error>
and when I run predictions against the trained NN model in the
"Mining Model Prediction" pane it predicts the same value for every
case in the testing set.
Any thoughts?

Hi,I am studying data mining features of SSAS and for a workshop I'vecreated 2 views derived from vTargetMail view of AdventureWorksDW.Train data consists every record except those in Pacific, and testview consists only records from Pacific area.1. I've created a mining structure based on Decision Tree and selectedBikeBuyer as predictable column.2. According to input column suggestions, I've selected Age,Eng.Education, NumberCarsOwned, YearlyIncome, CommuteDistance,NumberChildsatHome and TotalChildren as input columns,3. I've modified no other setting, and deployed project.I can get training results in decision tree browser and dependencynetwork (and both seem to give rather logical results) however, when Itry to browse lift chart or classification matrix I get an emptyclass.matr. and a lift chart of a single 45 degree line.Am I missing a step, or must I do some fine-tuning on (what)parameters?Thanks...

Hi, all experts here,
I am a bit confused for the model evaluation (lift chart), should we map all the columns for both the mining structure and the case table? I mean for those predictive models, we have a predict column, shouldnt we ignore the mapping of the predictive column between the mining structure and the case table? But it seemes we are not allowed to miss the predictive column mapping between the mining structure and the case table.
Why is that? Could any experts here give me some explanation on that?
Hope my question is clear for your help.
Thanks a lot and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,

2) Line chart that has the same data as per the above points on the bar chart but this is a running total. (3 series)
3) These data points are for the 12 months
4) there should be a secondary axis for the cumulative one
Can I create this using the same data set?

We have a line graph which plots the actual data points (x,y), everything is working fine with this graph. Now we need to add a trend line to this existing graph after going thro. the articles we came to know that there is no direct option in SSRS to draw a trend line. So we need to calculate the trend values ourselves which we need to plot as atrend line. This trend line is similar to the trend line which comes in Excel chart, do anyone know how to calculate the trend values from the actual data points. We got through several formulas, but were not clear, have anyone tried out exactly the same, if so please help us out by providing an example to calculate the trend values.

Hi,
I have just run a simple data set through a model to predict a simple true or false value (i.e. binary output)
The Lift Chart/Mining Legend in Analysis Services shows three results €“ Score, Population Correct (%), and Predict Probability (%)
Population Correct I beleive is the percentage of predictions it got right out of the total number of predictions it tried to make. Is this correct?
However, I can€™t work out how the other two are derived in particular the 'SCORE'. To give a live example the scores were as follows:
Model Score Pop Correct Pred Probability
Decision Trees 0.83 76.59% 54.28%
Neural Network 0.75 67.63% 50.05%
Ideal Model 100.00%
Can anyone help with this and give a detailed explanation?
Many thanks,
S Rajput

Hi
Anyone have any idea how to make a line style dashed or dotted in a line chart please?
If I change the series style to dashed or dotted it still appears as a solid line, yet the legend displays a dashed or dotted line....

Hello,
My line chart displays all lines in a single color (the series color). I'd like a single color per item in the series just like the bar chart. Is there a way to change this? Or is the only differentiation the markers?

am using a line chart to display series of results over time - data is got from and AnalysisServices cube.
problem is that sometimes there is no value for the result - and the chart doesnt display that as zero
e.g. with the following data
week 1 10 items
week 2 12 items
week 3 14 items
week 4 8 items
week 6 12 items
the chart will join the week 4 result of 8 items directly to the week 6 result of 12 items
is there anyway of changing this so the line goes from 8 items on week 4 to ZERO items on week 5 and then 12 items on week 6 ???

I want the top level AHT the first chart should be 13.66 the second one should be 8.01.

Good day,
Is there anyway that I can have a multi-line chart title? I have even tried placing a text box over the title part of the chart that is multi-line, although this appears to work once the report is deplyed and viewed in a web browser the text box appears below the chart and the chart then has no title.
Please can you help?

I create a rdlc file that contains a line chart with 3 lines that will plot in it. I put the proper data field in "series" and everything plots fine, except I get a spurious line that goes from the end of one line to the start of another line (or possibly back to itself, I can't tell). In another line chart I have 3 lines but get 2 spurious lines.
Anyone know how this happens or how I can fix it? The data is ordered and I don't see anything that would cause this..
Thanks,
Craig

Hi,
Two questions both on Line charts:
Is it possible to give the marker of a line chart a different colour from that given to the line?
Is it possible to make only the line in the line chart invisible? My requirement is to keep only the markers.

So I have created a chart in my report that counts the number of transactions by day. Each day in a month is a series. Now when I view the report, the series line is different color as expected until I hit the 17th, then the color associated with the line repeats. I.e. the 1st and the 17th are the same color line, the 2nd and the 18th are the same color...etc.
Does anyone know how to break the color limitation quandry?
Thanks.

I have a report I'm writing and have got a problem that has stumped me.
The data the report is based in is in this format:
Date Type
1/1/08 A
1/3/08 B
3/1/08 C
3/5/08 B
3/10/08 A
3/12/08 C
3/20/08 A
Management wants a report showing a line chart that summarizes the data by Month and by Type. So, there are 2 series depending on the Type and data values are based on the count of each Type. So, in the example above the x-axis group would be month, the values would be count(Type) and there would be 2 series €“ Series 1. A, B and Series 2. C
I€™ve defined the x-axis to be Month(Fields!DateOccured.Value). However, they want the x-axis to show every month for the entire year not just what is in the database. So, I defined the x-axis to have a scale of 1 to 12 and the major interval is set to 1. This displays 1 through 12 on the x-axis.
The problem is when there is no data (null) for a particular month. Instead of showing 0, the line chart does not plot anything and the line is drawn to the next displayed point. So, for example on the data above the line chart would plot:
January
Series 1 €“ Qty. 2 Series 2 €“ Qty. 0
February
Null
March
Series 1 €“ Qty. 3 Series 2 €“ Qty. 2
The line chart would draw a line from January to March skipping February. I need to display the null values as 0 and not null indicating no occurrences for the month rather than no data present.
Thanks!

Hi,
I am having a report which contains a line chart. I have tried different alternatives, but i could not get it solved.
For example:
Line Chart with
x-axis : month(1,2,....,12)
y-axis : sales amount.
series group : city (DimGeography.City) filtered by (DimGeography.StateProvinceName = "London")
I am getting different lines for different cities of London. That's working fine. But the requirement is i need to display one more line in the same line chart depicting/showing the sales for the "London" state as well.
Please help me if anyone can.
Thanks in advance.

I am creating a simple line chart using SSRS 2005. The chart will display date vs. cumulative enrollment. In the line chart I want to display two lines. One line represents expected enrollment data and the other represents actual enrollment data. I would like the expected data line to be a dashed line and the actual line to be a solid line. I have a single dataset that contains data for both lines. I have added a column to the dataset that acts as a flag to indicate whether the data point is expected or actual. I have dropped the enrollment field from my dataset into "Drop data fields here". I have dropped the date field from my dataset into "Drop category fields here". I have dropped the flag field from my dataset into "Drop series fields here".
When I change the style of the series it changes the styles of both lines. How can assign a different line style to each line? Is this even possible with the way I have set up the chart? Is there another way to set up the chart to accomplish what I am trying to do?

Is there a possibility in SSRS to have  One stacked bar of cumulative sum of different ID's and and Line Chart at left hand of the Bar which will show the Progress as soon as the ID turn to Competed status.
I have been trying to do this , however there is huge problem of scaling:
The line should be finished at all the completed ID's SUM which is the lowest stack of the Bar.
However , the bar gets stretched to all of the space.
I have tried to place it into Tab lix, But it doesn't work.
