<DIV dir=ltr><FONT size=2 face=Arial></FONT> </DIV>
<DIV dir=ltr><FONT size=2 face=Arial>I am trying to run a series of models using the glmmADMB function with several different distribution families (e.g., poisson, negbinom). I am using a Optiplex 790 PC with Windows 7, 16.0 GB of RAM and a 64-bit operating system. I am running R version 2.15.0 and started out using the most recent version of glmmADMB (I believe version 7.2.15). My data is zero inflated count data that is overdispersed. When I ran the following code for either a zero inflated poisson (family="poisson") or a neg binomial (i.e., family="nbinom"):</FONT></DIV>
<DIV dir=ltr><FONT size=2>fit_zipoiss1 <- glmmadmb(LOCS~D_ROADS + (1|YEAR) , data=FAWNS, zeroInflation=TRUE, family="poisson", mcmc=TRUE)</FONT></DIV>

<DIV dir=ltr><FONT size=2 face=Arial>As suggested by previous users (specifically Ben Bolker) I downloaded an earlier version of glmmADMB ("glmmADMB_0.7.tar.gz") and re-ran the same models (e.g., poisson and neg. binomial) and received the same error. A</FONT><FONT size=2 face=Arial>s suggested by Mr. Bolker and others I also tried running both a poisson and neg. binomial model with "admb.opts=admbControl(shess=FALSE,noinit=FALSE) " and received the same error.</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=Arial></FONT> </DIV>
<DIV dir=ltr><FONT size=2 face=Arial>I am not sure if an even older version of glmmADMB (i.e., glmmADMB v. 0.6.5) would work as it seems to have worked for others but I am unsure of where I can find this version?</FONT></DIV>

<DIV dir=ltr><FONT size=2 face=Arial>Any suggestions would be very much appreciated. Thank you for your time.</FONT></DIV>
