    Hi  Anonymous ,

     

    Take try of this one:

     

    Concordant = 
VAR __table = ADDCOLUMNS(VALUES(PMS_COMPLAINT[FISCAL_MON_START_DT]),"CountComplaints", CALCULATE(COUNTROWS(PMS_COMPLAINT)),"__Index",RANKX(PMS_COMPLAINT,PMS_COMPLAINT[FISCAL_MON_START_DT],,,Dense))
VAR __count = CALCULATE(COUNTROWS(__table),FILTER(__table,[__Index]<=MAX([__Index])&&[CountComplaints]<=MAX([CountComplaints])))
RETURN
IF(ISBLANK(__count),0,__count)

you need to tell earlier what to reference. Can try wrapping an ALL around the table and see if that would work. But would be easier if you can upload some sample data with the required output.

i am referring to the folloiwing Kendall's Tau Quick Measure here https://community.powerbi.com/t5/Quick-Measures-Gallery/Kendall-s-Tau/m-p/625107

 

I am trying to re create the same calculation using my dataset. Sample file attached. I am trying to get the tau

 

The values i would like to use from my data set are Material_id and FISCAL_MON_START_DT as the two variables. Which find these in the main FACT table PMS_Complaints.

 

The answer lie with the greg decker link on how you can implement the measure....he uses two variables and sorts the data interviewer 1 and 2. I want to implement the same principles with my data using variables as I mentioned in above post...

 

Smaple Data File

for required output see tau value in image (below)

currently my tau value is 0.186441 as you will see from first tab when you open up pBIX file. i am trying to make this measure dynamic.
