Re: [Gretl-users] Dataset handling in gretl (IDs, labels, standardization)

> >> (3) Finally, I would like to standardize the regressors (not the dependent variable) in my dataset, such that each regressor has mean 0 and standard deviation of 1. Is there a "summary way" to do this e.g. by declaring the dataset to be a matrix, then operating on this matrix using some matrix operators? > I guess you could do this by using the "meanc" and "sdc" commands. Or, better try the following script <hansl> open australia.gdt matrix my_std_matrix = {} loop foreach i PAU..IUS mymean = mean($i) mysd = sd($i) my_std_series = ($i - mymean)/mysd my_std_matrix = my_std_matrix ~ {my_std_series} endloop _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
