Is there an equivalent of Excel's PERCENTRANK (column,value) in SQL? I think native SQL Server functions provide only percentiles from the same column, but am I missing something?
The problem is that I have two columns - A and B - and I need to use distribution of values from column A and then take values from another column and rank them against column A - how do values in B fit in distribution defined by column A (or, precisely: get CDF of column A at point defined by B).
Possible solutions:
- Write UDF (they don't parallelize, do they?) - can you answer how could I efficiently structure such UDF?
- Use SQL Server 2016 and integrate it with R (R code within SQL code)
- Copy data to R, perform calculations, send back to server
- Copy data to Excel and calculate it over there "manually", import results back to database
There are multiple columns with values and distributions I need to apply this strategy to, so I am looking for an efficient solution.
Edit - example:
column A column B result
10 16 0,20 =PERCENTRANK($A1:$A4, B1)
20 35 0,83 =PERCENTRANK($A1:$A4, B2)
30 10 0,00 =PERCENTRANK($A1:$A4, B3)
40 25 0,50 =PERCENTRANK($A1:$A4, B4)
