Edward, you also can use the package aod on CRAN, see the help page of the function negbin. Best Matthieu An example: > library(aod) > data(dja) > negbin(y ~ group + offset(log(trisk)), ~group, dja, fixpar = list(4, 0)) Negative-binomial model ----------------------- negbin(formula = y ~ group + offset(log(trisk)), random = ~group, data = dja, fixpar = list(4, 0))

I have tried glm.nb in the MASS package, but many models (I have 250 models with different combinations of predictors for fish counts data) either fail to converge or even diverge. I'm attempting to use the negbin function in the AOD package, but am unsure what to use for the "random" term, which is supposed to provide a right hand formula for the overdispersion parameter.

I have fitted the faults.data to glm.nb and to the function negbin from the package aod. The output of both is the following: summary(glm.nb(n~ll, data=faults)) Call: glm.nb(formula = n ~ ll, data = faults, init.theta = 8.667407437, link = log) Deviance Residuals: Min 1Q Median 3Q Max -2.0470 -0.7815 -0.1723 0.4275 2.0896 Coefficients:

Hi, can anyone help me fit betabinomial model to the following dataset where each iD is a cluster in itself , if i use package aod 's betabinom model it gives an estimate of zero to phi(the correlation coeficient ) and if i fix it to the anova type estimate obtained from icc( in package aod) then it says system is exactly singular. And when i try to fit my loglikelihood by

Hi, I'm looking for a way to force users to use a pty and their login shell. They have a .profile that forces them to use a specific application. They are currently logging in with telnetd, so this is effective. I want to move to openssh, but this would allow "ssh user at host /bin/sh" and any other commands they can think of to bypass this restriction. Is there a way to

Hi, Just a quicky, I can't see anything about how Dovecot handles certificate chains. 1, Does it handle them? 2, How, if if does? (Just got a cert from www.instantssl.com and I need there intermediate cert do validate it.., Works fine with Apache and Exim ) Cheers, Steve Gare - Xantara.Net -- 0845 123 5707

Hi, Been using Dovecot for a few weeks now, must say it's very good.. I've been looking for a 'drop in' replacement for UWImap for ages! :) but just recently It's been giving me a few problem, I haven't tracked down exactly what causes the problem yet (I'm using Apple Mail on OS X 10.2.6) but after a good mail session it keep trying to log in over and over again..

Hello, I try to implement a samba server (2.2.7a) with the authentifiactions via winbind to a PDC W2000. When I test winbind, it works: [root@pxtest samba]# wbinfo -t Secret is good [root@pxtest samba]# wbinfo -a tli%password plaintext password authentication succeeded [root@pxtest samba]# I enable the winbind on the /etc/nsswitch.conf: passwd: files winbind shadow: files group:

Hi, I had a linux server installed with samba 3.0.9-2.6 (SuSE 9.1) and a samba shared folder among 12 PC under WinXP/Win7. The linux server has been replaced by a new one a week ago. The new machine runs samba 3.5.4-5.1.2x86-64 with the same shared folder and the same smb.conf file. Till then, when the PCs try to connect to the samba share via explorer a window opens with the message "Num?ro

Hello, I am actually developping a libary under S+/NT in which I do modify the .Program. Is there any equivalent in R?
