Simple Linear Regression On Multiple Data Fields
Mar 25, 2013
I have a Table that looks like the following:
A B C D E
10 12 8 4 14
9 10 7 5 12
12 13 10 3 17
10 11 6 6 15
I have figured out how to calculate the regression statistics for A vs B on a query. So it looks like this...
Predicted B Difference between
A B m b via regression Predicted and Actual
10 12 .9474 1.7895 11.263 -.737
9 10 .9474 1.7895 10.316 .316
12 13 .9474 1.7895 13.158 .158
10 11 .9474 1.7895 11.263 .263
Question: What I am looking to do is to duplicate this for A vs C, A vs D, A vs E, B vs C, B vs D, and so on until all of the pairs are calculated and put into one table/query. I know I can just create more fields to the right with the A vs C data and continue on that way, but this does not seem very efficient and I am limited in the number of fields that can be created. So it seems that "going down" rather than across makes more sense however I do not know how to move on to the next pair (A vs C and so on).
I thought of running the regression query over and over again and "recording" the data generated into a table. Once again I have the same problem. How do I tell the regression query to run the next pair? If my data is setup incorrectly, I am willing to change that as well.

I have (from SPSS) many multiple regression analyses, and each one of them has about 7-8 independent variables. I need to find the effect size-in particular I want to have effect size above 1% and statistical significance p<0.001. I am familiar with p, but I cannot understand whether effect size is b, beta or R square and how to interpret it.

I've been searching in vain for a solution to a relatively simple bit of mathematics that I’d like to Access to undertake.
It involves interpolating between data, as illustrated in the following example. Basically have several items, and let's say different "prices" dependent on the number of units purchased. The relationship between the “prices” is not a straightforward formula, therefore I need a query to return an interpolated price for a given number of "units".
DATA
ItemID Price10Price20Price35Price50Price100Price 1000
1£70£135£200£315£800£6500
2£23£31£61£89£210£1500
OUTPUT
ItemIDUnitsPrice(int)
117?
231?
So, for example
if Units <10, Then Price(int) = Price10
if Units = 17, Price(int) = Price10 + (17-10)*(Price20-Price10)/(20/10)
if Units = 32, Price(int) = Price20 + (32-20)*(Price35-Price20)/(35/20)
if Units >1000, Then Price(int) = Price1000
I'm aware that IIF statements might do the job, but I have 15 different 'Price' points, and don't particularly want to nest them all.
This problem was solved previously in Excel using a clumsy set of VLOOKUP/HLOOKUP functions in conjunction with If statements.

I have tables that are ODBC linked to a SQL database. The source tables have record date and time stamps written into one field. This means that I can't use the Access date filter functions on these fields. Is there an easy way to parse this field into two fields, one each for the date and time?

Hello All,
I'm trying to limit the data entered into a specifc field, but also the data must be unique with respect to other fields.
i.e.
Two fields: System A & System B.
Data entered into System A, can not be entered into System B.
Anyway to prevent this from recurring?
Would I use a validation rule?
Thanks in advance

Hi All
Been handed a contacts database, one field of the DB includes all the industry sectors associated with the customer, with multiple industry references separated only by a comma within the field (e.g. Insurance-Life,Insurance-Broking,Insurance-Motor,Insurance-Pensions,Insurance-Home,Insurance-Health) – I want to split this one field into multiple fields using the comma as the break point (this is something that’s relative easy to do in Excel with the ‘Text to Columns’ tool – but unfortunately it can’t take the 130,000 odd records of the databasel)
Can any one recommend an expression or method that will see the 6 industry references split into 6 separate fields ?
Thanks
Jim

Access2007- Building a query to handle future input...
I run an update query that does what it is supposed to do and gives the proper values.
THEN I add a one more field to the source with the builder using + that has no data in it yet, the query fails and gives blanks, even though one of the fields in the source has data in it.
I would think that the "no data" field would be considered 0.00 value and be added together to the field that has values giving at least the value of the field with values as a result of the query.
Is there a setting somewhere that I need to change so that the no value and the value would be combined? I am using the builder to combine the values in the query.
Thanks.

I imported a big table from excel with many columns. Access when I brought it in determined that they should be "text" format. I don't want to sit and change each field to a "number-double". Is there a way to quickly change data type for multiple fields at once?

I am trying to create the form so when the first field (Start Date) has a date selected, it limits the following field (Report Date) to the matching available data, and same with the third field (Production Division) on the previous two.
I also need the form to allow new dates / production division combinations, but not duplicate.
I starting working with a cascade function but got confused and not sure if that is where I should be headed.
I have attached 2 different formats of the same sample data.

I have an access table that looks like the below:
"field1", "field2, field3, field4, field5, field6, field7"
"field1~field2~field3~field4~field5~field6~fie ld7"
"field1~field2~field3~field4~field5~field6~fie ld7"
"field1~field2~field3~field4~field5~field6~fie ld7"
"field1", "field2, field3, field4, field5, field6, field7"
"field1~field2~field3~field4~field5~field6~fie ld7"
I've got a module which loads the data into a table, but it can't handle the records that are ~ delimited, so spits them out as a single field.
I know there is some VBA code that can be used to split comma delimited records, and I've seen bits of it floating around online and tried to alter it to work for the ~, but I get the feeling that what I've seen is only a part of the required code, how to put it all together to make something that actually works.
So, what I need to do is;
- Split some records in a table out into multiple fields where there is a ~ present
- Place these newly split fields into a table (I don't mind if it ends up in a new table or not)

"Dynamically search multiple fields" using my own customer data.
I'd like to add in additional searches as what he has will let you do one search but I'd like to, in his example, search on vintage and state, or the like. I assume Id need two multi-searches for this.
Right now the data is in excel so I have a completely blank page to fill.

Let's say I have a table called "Courses" which among other things has "Completed"(Yes/No) and "Category"(Text).
Now, there also another table "Progress" which has similar columns.
I want Progress.Completed to reflect if all courses of the specified category have been completed.
How would I do that? I'm new to access ...

I'm creating a query from one table using two fields that require certain records to NOT bring up records that have the following text:
One table, two fields
First field ECO LifeCycle Status Criteria is Not "ERP UPDATE" or "CANCELLED"
Second field ECR LifeCycle Status Criteria is Not "COMPLETE"
When I put the Not Criteria in the first field only I get a result.
When I put the Not Criteria in both fields I get no results.

Access 2010
I have a form bound to a table which has 20 (name)fields and 1 date per record. A user fills in this form first to indicate which people are present this day. I know it would be better to use 1 name per record but that would in this case not work since the form must show all names for that day before saving and closing.
I have a different form where I use 4 combo boxes and a date field. The values that can be selected in the combo boxes should come from the 20 names on the first form and with the same date as the other form. So only 4 people of the 20 indicated as present on that day can be selected to have performed some task.
I know how to select with a combo box from different records, but how would I do it from different fields in the same record? And then also for a particular date?

I'm running an update query that's based on a select query (that runs some calculations). The update query is updating ALL the rows that should be updated with the information in the select query with data from the final row in the select query, and not on a per ID basis as I think I have it set-up to do. The data looks correct in the update query, but again it's not coming out right.
Here's the SQL for what I've written so far:
UPDATE [Customer_Data Query], Customer_Data INNER JOIN Baseline ON Customer_Data.ID = Baseline.ID SET Baseline.[Unit Hours] = [Customer_Data]![Dur_Days]*[Customer_Data]![Dur_Hours]*[Customer_Data]![Number_Units], Baseline.Availability = [Customer_Data]![Perceived_Avail], Baseline.[Hours Available] = [Customer_Data]![Dur_Days]*[Customer_Data]![Dur_Hours]*[Customer_Data]![Number_Units]*[Customer_Data]![Perceived_Avail],
[Code] ....
I've also tried to force the update to the proper row by adding a criteria based on ID.
Select query, here it is:
SELECT Customer_Data.ID, Customer_Data.Data_Set_Version, Customer_Data.Number_Units, Customer_Data.Perceived_Avail, Customer_Data.MTTR_MTBF, Customer_Data.MT_TR_OR_BF_Hours, Customer_Data.Utilization, Customer_Data.Percent_Scheduled, Customer_Data.Sched_Percent_of_PM, Customer_Data.Sched_PM_Duration, Customer_Data.Sched_CBM_Duration, Customer_Data.Sched_CBM_From_PM, Customer_Data.React_Detect, Customer_Data.React_Rework, Customer_Data.React_False_Alarms,
[Code] ....

I had an existing database with 2329 records entered into it. All of the fields (220ish) were all in one table. Myself and my co-workers wanted to rebuild the database without losing the data. We wrote queries to transfer the data from the original database to the new database and split the data from the original 1 giant table to 9 smaller tables.
The transfer of data worked so I went to start making forms. When I went to add fields from different tables I had to built a relationship, which I did. All of the data that transferred over from the new database is in the form (now multiple forms linked by button) but I can't add new information. I get an error stating, "You cannot add or change a record because a related record is required in table ..." and the table referenced keeps changing.

I'm used to doing a data analysis but never had much cause to use Access previously so I'm trying to quickly pick up the essentials for a specific work project:
I need to extract a subset of data from an Access 2000 database and then perform some category operations on that subset - all interactively. So 2 questions please:
1. I'd prefer to do this with two successive queries (just so the logic is plainer to me) the second operating on the results of the first. But I can't immediately see how to submit the results of one query to a second query interactively.
2. If I were to combine both queries into one can I safely assume that the columns will be processed from left to right (as shown in the query designer)? To explain: I want first of all to select a subset of the data and then to do some stats (ie as a 'total' field) on the subset. But I need to ensure that the stats are done on the subset and not the full original table.
TIA

I want to create a form that allows users to update multiple fields for multiple assets. Below is what I came up with:
Ideally, I'd like the subform to be filled in by having the user select multiple Assets from the S/N combobox field which would then auto-populate the "Type" field. Then they would fill out the appropriate fields they want edited in the top part of the form. They hit save and magic happens. This would also be nice because only assets they want edited would be displayed (easier on the eyes) and no distinguishing would be necessary. To do it this way, I know I would need to use a temp table but I wanna avoid using temp tables.
I know I can do this by adding a Yes/No field in the "Asset" table, setting the "Asset" table as the subform's recordsource, and then putting a checkbox in the subform and allowing them to check the assets that they want to edit (which would also allow me to sort it instantly so that checked Assets are at the top of the datasheet for easy viewing), but I would like to know if there's a way of accomplishing this without the use of checkboxes.
I know I could also use a listbox and that allows them to multi-select items, but I'm not sure if that allows me to group all selected items at the top of the listbox for easy viewing of selected items. Plus it would involve a lot of scrolling (there are over 2k assets).

A small issue I was wondering of for a few day . Is it possible in SQL query to SELECT multiple fields from multiple tables ? Example for the question is
Code:
dim my_var as String
my_var = "SELECT Emp_FName , Emp_LName , Emp_Adress " _
& " FROM Table1 " _
& " AND Emp_Date_Of_Payment , Emp_Sum_Of_Payment " _
& "FROM Table2 " _
& " WHERE Emp_ID = 3 "
Is this code actually valid in SQL gramatics , and is it usable if passed to a Recordset variable ( rs = CurrentDB.OpenRecordset(my_var) ) ? Just FYI - The two tables are not related and I want to keep them that way (If possible relate their records just via SQL/Vba )

I created the below query to come up with a new form. When I enter a single parameter, it works fine. When I modify the code and enter multiple patameters, it also works fine if I do not enter any information for the parameters. But once I enter one of the parameters information, then it does not come up with anything. I double checked and made sure it was typed in correctly. Is there a trick when entering multiple parameters on a query?
SELECT [JE 06 Log].[Operational Region Name], [JE 06 Log].[Period Name], [JE 06 Log].[Source System], [JE 06 Log].[Source Name], [JE 06 Log].[Category Name], [JE 06 Log].[Associated Category Name], [JE 06 Log].[JE Name], [JE 06 Log].[JE Base #], [JE 06 Log].Area, [JE 06 Log].[Line Description], [JE 06 Log].[Natural Account], [JE 06 Log].Description, [JE 06 Log].[JE Entry Date], [JE 06 Log].[Debit Amount], [JE 06 Log].[Credit Amount], [JE 06 Log].Amount
FROM [JE 06 Log]
WHERE ((([JE 06 Log].[Period Name])=[Enter Period]) AND (([JE 06 Log].[Source Name])=[Enter Path]) AND (([JE 06 Log].[JE Base #])=[Enter Base Number]) AND (([JE 06 Log].[Natural Account])=[Enter Natural Accnt])) OR ((([Enter Period]) Is Null) AND (([Enter Path]) Is Null) AND (([Enter Base Number]) Is Null) AND (([Enter Natural Accnt]) Is Null));

Hi i've read a few post regarding sharing db accross a network but still not too sure if i'm doing it correctly. please bear in mind i'm new to access.
ok so far i've created my database (db1.mdb) which consists of 1 table 2 queries & 1 form.
i've placed this on my XP pc which is my dedicated server, Access is installed on this pc.
i've split the data base which creates db1_be.mdb, now am i correct in thinking that db1_be.mdb is the back end file which needs to be placed on my local pc's.? i've also linked to the table & sorted out all the permmisions stuff.
but i loose my queries & form.? (on the local pc)
what i really want to be able to do is store the database on my XP (server) pc & each user only requires the form to be available strickly for data entry only.
i may need to modify the form or queries at a later date but this will be done from 1 pc. am i on the right track.?
many thanks for any help in advance.
John :confused:
