great! welcome!Dear gretl community, I am using gretl Yes, through the "Variable-> edit attribute" menu (or right-click on the variable) and change the ID number.(1) Within gretl, is it possible to change the ordering of variables, and keep i.e. save this changed ordering? Mmmm, can you try the "Data -> Observation markers" menu? I know there's a similar stuff to add/remove the variables labels (the "Data-> Variables labesl" menu) but never tried with observations'.(2) Within gretl, suppose a dataset contains observation labels e.g. company names. Is it possible to remove all observation labels from the dataset so that there are none? I guess you could do this by using the "meanc" and "sdc" commands.(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? Hope it helps,Could anyone provide an idea how to resolve these issues, please? I'd appreciate this a lot. Artur |
