I am trying to do some linear regression analysis in my cube so that i can the use this to forecast future revenue. I have written all the calculation script and deployed it successfully but there are no results being returned and i cannot figure out where i have gone wrong.I'm hoping someone here can help me before i go mad staring at the code, i am pretty sure it is something to do with how i have set-up the Rolling 12 Months Set but cant see the problem for looking..Additionally I only have data spanning back to august last year if that makes any difference to how the results are producedHere's the code.[code="sql"]CREATE DYNAMIC SET CURRENTCUBE.[Rolling 12 Months] AS {strtomember("[DIM Date].[Date].[" + cstr(year(dateadd('yyyy',-1,now()))) + "-" + Right('0'+ cstr(Month(now())),2) + "-" + Right('0'+ cstr(Day(now())),2)+ "]") :strtomember("[DIM Date].[Date].[" + cstr(year(dateadd('yyyy',-0,now()))) + "-" + Right('0'+ cstr(Month(now())),2) + "-" + Right('0'+ cstr(Day(now())),2)+ "]")};CREATE MEMBER CURRENTCUBE.[Measures].[Rank 12 Months] AS RANK([DIM Date].[Year Month Key].CurrentMember , ORDER([Rolling 12 Months] , [Measures].[Month Key] , BASC ) ), VISIBLE = 0;CREATE MEMBER CURRENTCUBE.[Measures].[12 Month Trend] AS iif( [Measures].[Completed Days] <27 ,null ,LinRegPoint([Measures].[Rank 12 Months] ,[Rolling 12 Months] ,[Measures].[Sales Amount] ,[Measures].[Rank 12 Months] ) ) , FORMAT_STRING = "Currency" , VISIBLE = 1 , ASSOCIATED_MEASURE_GROUP = 'Sales Measure' ;[/code]Thanks in advance for any help or advice anyone can give me.
