Hi,
I have 3 variables (var1 var2 var3) each with 5 categories (1, 2, 3, 4 & 5).
I would like to create a variable, var4, showing overall total counts of the observations in 1's, 2's, 3's, 4's and 5's combined.
so that command tab var4 will give 1 (being sum of, 1 of var1 + 1 of var2 + 1 of var3) and 2 (being sum of, 2 of var1 + 2 of var2 + 2 of var3)...

and at the end, the overall mean and standard deviation of var4.

Thank you in advance,
Immac
