Hi Julio,

I think you can try the stats X-Function.

Suppose you have selected some rows of a column and want to save the mean of them to a variable named mymean and their sd to mysd. Use the following script:



stats mean:=mymean sd:=mysd;
mymean=;
mysd=;


Please see more details on this X-Function here:

Many thanks Deanna. It works beautifully.

I came across your stats information provided but I was unable to get the code, specially because the ix:=code.

I worked around other solution by marking those rows I did not wanted to be included in the sum(col(x)) function but yours is more simple.

Again thanks, julio
