We have repeatedly determined a whole bunch of "phenotypic measures" on
a group of individuals, over a period of three years now. I would like
to use Stata to perform analyses of the data, but I'm a real newbee.
In my datalist I have one line per subject (individual) for every single
time the individual was tested. In columns, I have the numerical values
for the different phenotypic measures. The same subject (individual)
does show up several times in the datalist (several lines), and
therefore, for every subject we have multiple independent determinations
of the same phenotypic values.
Is it possible to generate new variables containing the variance of the
measurements, per subject (individual) ?
I hope you can give me some clues ...
Jan
