<div style><font color="#222222" face="arial, sans-serif">Dear glmmADMB users,</font></div><span style><font color="#222222" face="arial, sans-serif"><div><font color="#222222" face="arial, sans-serif"><br></font></div>Yesterday I was running my full & reduced models with several different distribution families and had no problems except for the warning message "Estimated covariance matrix may not be positive definite" followed by a string of numbers for a few of the distribution famlies. But when I ran the summary() command on the model everything seemed fine. I decided I would update to the latest version of glmmADMB to see what happens. Ran the same models and the warning was gone. Great! </font></span><span style>I was on Mac OSX 10.6.8, running R v.2.14.0 64-bit, and package glmmADMB v.0.6.5 and updated to glmmADMB v.0.7.2.5.</span><span style><font color="#222222" face="arial, sans-serif"> I ran the following distributions: poisson, zero-inflated poisson, negative binomial, zero-inflated negative binomial, and negative binomial type 1. Today I come back to continue working on reduced models and I get the following error: </font></span><div>
<span style><font color="#222222" face="arial, sans-serif">Error in glmmadmb(count ~ treat + bromleaf + (1 | tree), data = ecpad, : </font></span><div style> The function maximizer failed (couldn't find STD file)</div>
<div style>In addition: Warning message:</div><div style>running command './glmmadmb -maxfn 500 -maxph 5 -noinit -shess' had status 1 </div><div style><br></div><div style>I have now gone through restarting everything, downgrading glmmADMB to v.0.7.2.4 then back to v.0.7.2.5, and upgraded R to v.2.14.1 with no luck. I looked for glmmADMB version 0.6.5 but couldn't find it. Just some preliminary testing with models that ran fine yesterday it appears that negative binomial (family="nbinom") and negative binomial type 1 (family="nbinom1") are the two that now give the above error. It is strange that zero-inflated negative binomial works fine. I have tried to follow the previous few posts about dealing with this problem but with no luch and its a little unclear to me if they were on a Mac or not for some of those remedies.</div>
<div style><br></div><div style>Really loving all the new functionality of glmmADMB so big thanks to the developers. Just bummed its not working for me now, particularly negative binomial type 1.</div><div style><br></div>
<div style>Where can I get the glmmADMB v. 0.6.5 that was working?</div><div style><br></div><div style>Thank you,</div><div style><br></div><div style>Shawn</div>
