There are several ways to do this.  -search min- and -search max- would
point you to them, although it wouldn't be immediately obvious which
links to click on.  Anyway, here are two:

-summarize varname- will create scalars r(min) and r(max).

-egen min_varname = min(varname)- will create a new variable containing
the minimum across all observations.

Hope this helps,
Alex

Subject: st: How to find the minimum and maximum values of a column?

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
