Hi all, 

I searched the help for how to convert a correlation of a set of variables 
to a Matrix. It tells me to use the command -matrix accum-. I tried it but 
it drops all my observations with missing data. eg if var1 contains 1 
missing data point, I should still be able to collect the pwcorr for var2 
and var3 using that record, but that's ignored in the matrix approach. Any 
fix to that? 

Second question is probably easier - how do you convert all the elements 
of a matrix to non-negative, ie taking the absolute? 

Thanks for your help. 

Tim
