[Gretl-devel] different treatment of d.o.f. correction between sd()/sdc() and corr()/mcorr()

Hi, I noticed that corr() and mcorr() produce the same results, but sd() and sdc() seem to use different divisors. This "diff-in-diff" seems to me a bit arbitrary, or is there some background story? Otherwise I'd say the functions should all use the same convention. (which one I don't care) thanks, sven example: <hansl> open denmark ols LRM const LRY IDE list lall = LRM LRY IDE matrix mcr = mcorr({lall}) print mcr matrix msd = sdc({lall}) print msd loop foreach i lall c = corr(LRM, lall.$i) print c s = sd(lall.$i) print s endloop </hansl>
