[Gretl-users] Grand mean centering, groupmean, cwc variable creation
Hi
Is there any option to create grand mean centering of a varibale x_mc, (x_i - x_bar),
group mean (x_barj), centering within clustered variable x_cwc (x_i - x_barj). These are
necesary functions to teach mixed models. If there are not, i request you to provide.
