ssas - How to calculate margin percent in MDX -

-

i have dimension divides single fact value members. ie. ([dim].[member1], value), ([dim].[member2], value) ..

can calculate dimension members margin single value?

using calculated member formula nested iif as:

create member currentcube.[measures].[margin]          iif([dim].[member1] = [dim].[member1].&[x],     sum([dim].[member1].&[x],[dim].[member1].&[y], value) / ([dim].[member1].&[x],value),      iif([dim].[member1] = [dim].[member1].&[y],     sum([dim].[member1].&[y],[dim].[member1].&[f], value) / ([dim].[member1].&[y],value),      iif([dim].[member1] = [dim].[member1].&[f],     sum([dim].[member1].&[f],[dim].[member1].&[y], value) / ([dim].[member1].&[f],value),      etc...

formula long, 150 rows :)

formula - R: how to pass in a reference to the variable in glm or lm? -

-
so let's have named vector: sorted = c(1,2,3) names(sorted) = c("a","b","c") and it'll following: > sorted b c 1 2 3 so vector named a,b,c, , has value 1,2,3 respectively. and have sample data: data.ex = as.data.frame(matrix(rep(c(1,2,3,4),3), nrow = 3, ncol = 3)) colnames(data.ex) = c("a","b","c") so data frame has 3 columns named a,b,c well. i want predict c using value in glm(): fit.ex = glm(formula = c ~ names(sorted)[2], data = data.ex, family = binomial(link = "logit")) but then, i'll keep getting following error message: error in model.frame.default(formula = c ~ names(sorted)[2], data = data.ex,: variable lengths differ (found 'names(sorted)[2]') i read article here , found as.name() function, still not working: http://www.ats.ucla.edu/stat/r/pages/looping_strings.htm and cannot find else thats similar problem. please, if the...
