How to create Percentile with MDX??
i got this function but i'm not success to follow up.
Percentile ( set, numeric_value_expr, percentile )
(set -> The set from which to get a tuple value.
numeric_value_expr -> A numeric value or an expression that returns a numeric value.
percentile -> A percentile. Must be between 0 and 100. )
Thank you
Hi, l would like to calculate 80% and 95% percentile of a column from my table in SQL server 2005. Does SQL server 2005 provides such built-in function, if not, how should l do? Any suggestion? (Suggest to MS : Please include percentile as a built-in function on the next services pack). Thanks and happy labor day!

Hello All,
Does anyone know how to do an expression that calculate percentrank and percentiles? I have a table with a list of transactions and their response time. I need to find the 75th, 90th, 95th, and 98th percentile as well as the percentrank of <=5 seconds, 10 seconds, 30 seconds and 60 seconds.
Any help is appreciated!
I am using sql server 2008 to calculate the percentile value for each column.
--Script
CREATE TABLE #Table (Score Varchar(4),Percentile int)
INSERT INTO #Table (Score)
VALUES
('80'),('55'),('125'),('99'),('75'),('130'),('37'),('73'),('151')
select * from #Table
I would like the result to be shown in 25,50,75,100 percentile values . Here is the example
Score | percentile
80 | 75
37 | 25
151 | 100
75 | 50
I need to find patients(MRN) who are in the 95th percentile for BMI.
create table dbo.TEST
(
MRN varchar(10),
ResultValue varchar(10)
)
insert into dbo.TEST(MRN, BMI) values( '611193','25.63')
insert into dbo.TEST(MRN, BMI) values( '128845','16.93')
[Code] .....
I'm trying to create a calculated field that gives me the avg 75 percentile.
Right now I get this value by doing the following:
Create data set:
Select top 75 percent <field>
from <table>
Then I create the following calculated field
Avg(Fields!<field>.value,"<data_set_name>")
But I wanted to be able to create a calculated field that gives me the avg 75 percentile without creating a separate data set to get the top 75 percent Value.
Is it possible?
Thanks!
I am stumped on a set-based approach for this one.
A cursor approach is straightforward enough, but i want to avoid that.
Here's my table:
create table StudentScores
(
id int primary key identity(1,1),
student_id int not null,
score int not null
)
with some sample data:
insert into StudentScores (student_id, score)
select 1, 10 union all
select 1, 29 union all
select 1, 50 union all
select 1, 53 union all
select 1, 45 union all
select 1, 10 union all
select 1, 29 union all
select 1, 50 union all
select 1, 53 union all
select 1, 45 union all
select 1, 88 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 23 union all
select 2, 54 union all
select 2, 55 union all
select 2, 34 union all
select 2, 56 union all
select 2, 78 union all
select 2, 98
What I want is, for each student, what is their 90th percentile score?
For a given single student, one possibility would be:
declare @studentid int
set @studentid = 2
select top 1 @studentid as student_id, a.score as [90th percentile score]
from
(
select top 90 percent score from StudentScores
where student_id = @studentid order by score asc
) as a
order by a.score desc
But I want this for all students, and not use a cursor.
Any ideas?
Thanks!
I am writing some scripts to calculate mean (avg) stdevs count and percentile_cont for some data..I am partitioning over multiple columns e.g. partition by year,month, day order by value..I performing unnecessary overhead as I throw away all but the last (or max) value in each window. (I use cte then select max from cte).That is I only care about the avg of the window in its entirety not specific subwindows.

Is there any way to get that numbers like RankWanted ??

Any good way to add a percentile calculation to a table in sql server 2008 r2?
I've got 4 fields and I'd like to add a 5th labeling the records according to the percentile they fall in for one of the fields.
