That was a great idea, Josh! I found a problem even when I tried a simple model. Do you have any idea why?
tob6 <- censReg(transfers.cap ~ 1, left=0, right=Inf, method="BHHH", nGHQ=20, iterlim=10000, data = pdata2) Error in uniqval[as.character(effect), , drop = F] : incorrect number of dimensions thanks! *Felipe Nunes* CAPES/Fulbright Fellow PhD Student Political Science - UCLA Web: felipenunes.bol.ucla.edu On Sat, Sep 24, 2011 at 3:38 PM, Joshua Wiley <[email protected]>wrote: > Can you fit a simpler model successfully?
