<> See http://www.stata.com/support/faqs/res/statalist.html#who for the people behind Statalist. Among other things, it says: "Statalist is not moderated." Nobody is bullying you, really. Nick just pointed out ways for you to help yourself before turning to others, which makes good economic sense. Note that other sentence in the FAQs: "Assume goodwill even if it is not evident". I hope you will continue to ask any questions on the list that you cannot answer yourself.

März 2010 22:21 To: statalist@hsphsun2.harvard.edu Subject: RE: st: FW: [...] Stored Data after the calculation In a way, I think, being a new Stata programmer and only started programming for 3 months, I am being bullied by Nick Cox (BTW, is he the moderator?). I think if I know the answer and/or if I have time to go through all the previous discussions in details back from 2002, I do not need to come here and ask for help. I hope he understands why people are joining Statalist in the 1st place. Is that the reason why this site was being set up for in the 1st place?
