Dear STATA list members,

I am working in a program to estimate an index similar to the Index of
Human Development (PNUD, various  years), and I need to find the
maximum and minimum value of several variables across 2500
observations, I will then use these values to normalize the variables.
I know how to find min and max values across rows, but I cannot find a
command to find these min and max values across columns, other than to
transpose the data set with xpose, or to transform my data set into a
matrix (but then I can only have a 800x800 matrix, right?)

I may be overlooking something very obvious, and I apologize in
advance, but any help would be greatly appreciated.

Thank you in advance,

Laura
