Hi Arne, my problem persists. I am still using censReg [version - 0.5-7] to run a random effects model in my data (>50,000 cases), but I always get the message.
tob7 <- censReg(transfers.cap ~ pt.pt + psdb.pt + pt.opp + pt.coa + psdb.coa + pib.cap + transfers.cap.lag + pib.cap + ifdm + log(populat) + mayor.vot.per + log(bol.fam.per+0.01) + factor(uf.name) + factor(year) - 1, left=0, right=Inf, method="BHHH", nGHQ=8, iterlim=10000, data = pdata2) Error in maxNRCompute(fn = logLikAttr, fnOrig = fn, gradOrig = grad, hessOrig = hess, : NA in the initial gradient If I sent you my data set, could you try to help me? I have been struggling with that for two months now. I hope you can help!
