Betreff: st: Loop over time
Hello Statalisters,
I have a small problem which I seem to be unable to solve. I have a
large panel dataset. But the creators of the data did not carry
variables such as race and gender beyond the first entry of an
individual in the dataset. I am attempting to fix this issue via
creating a simple loop but get an error message that time series
operators are not allowed (even though I have declared the dataset
xtset, and even tried tsset). Below I provide an examples of the data,
all help is much appreciated, as always. Dmitriy
