The quick method: matrix pmx = values(pmean(x)) But if two or more panel groups have the same mean for x this will drop the duplicates, which is probably not what you want. In that case you can ensure you get the full vector of means via genr time series tmp = pmean(x) smpl time == 1 --restrict matrix pmx = tmp smpl --full Allin Cottrell _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
