What I would like to know is why when I use summary(model) the output only gives (what appears to be) the count process result. I.e. the binomial process, that deals with the zero/non zero is not shown. If you use zeroinfl() from library(pscl) it gives both ‘Count model coefficients (poisson with log link)’ AND ‘Zero-inflation model coefficients (binomial with logit link)’. The glmm.admb output seems to give only the count model coefficients. I am using glmm.admb rather than zeroinfl() because I have a random effect. Can anyone tell me whether is a way I could extract the zero-inflation model coefficients from a glmm.admb model?<o:p></o:p></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Many thanks,<o:p></o:p></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Daisy<o:p></o:p></div><div style="margin-top: 0cm; margin-right: 0cm; margin-left: 0cm; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div></div><br><font face="Arial" color="Maroon" size="2"><br>The University of Aberdeen is a charity registered in Scotland, No SC013683.<br></font>_______________________________________________<br>Users mailing list<br><a href="mailto:Users@admb-project.org" style="color: blue; text-decoration: underline; ">Users@admb-project.org</a><br><a href="http://lists.admb-project.org/mailman/listinfo/users" style="color: blue; text-decoration: underline; ">http://lists.admb-project.org/mailman/listinfo/users</a><br></div></span></blockquote></div><br></div></body></html>
