[Gretl-devel] clustered standard errors, 'period' keyword, driscoll_kraay

Hi, in short: --cluster=period works as announced, but with two-way clustering --cluster=period,unit doesn't work, one has to create a series mimicking the period (e.g., genr time). I guess this is an oversight and not intended. Also, Allin, off-list you said that "set panel_robust driscoll_kraay" now is a further option, but with yesterdays's snapshot I'm getting an invalid value error. Is this in a different branch or not pushed or something? thanks sven
