st: Changing positive values to negative in Stata
I have a continuous variable with positive, negative, and zero values
and also missing values(.).
I would like to know if anyone has an easy Stata code/command to change
just the positive values to a negative (change the sign: 4.4567 to
-4.4567) for just a particular subgroup of the total (n=661 out of over
N=4,000). Within this subgroup (which I can sort, but not by id) there
already are a few appropriately negative values in place.
Thank you,
Suzy
