Have a look at the warning in ?geepack::geeglm It should be mentioned in ?geepack::geese as well.

I used package "geepack". When I use the correlation structure "unstructured", I get a messeage that- R GUI front-end has stopped working. Why this happens? What is the solution? The r codes are as follows: a<-read.table("d:/bmt.txt",header=T") cutoffs<-c(1.75,3.34,5.09,6.93,9.11,11.8,15.3,20.1,23.7,27.3,30.9,34.3,37.6,41.5,46.5,51.1,57,63,73.1,93.68) a$icr <- REL library(pseudo) pseudo <- pseudoci(time=a$TIME,event=a$icr,tmax=cutoffs) #rearranging data b <- NULL for(it in 1:length(pseudo$time)){ b <- rbind(b,cbind(a,pseudo = pseudo$pseudo[[1]][,it], tpseudo = pseudo$time[it],id=1:nrow(a))) } b <- b[order(b$id),] library(geepack) fit3 <- geese(pseudo ~ as.factor(AGE) + as.factor(WEIGHT) + as.factor(HEIGHT) , data =b, id=id, jack = TRUE, scale.fix=TRUE, mean.link = "logit", corstr="unstructured") #The results using the AJ variance estimate cbind(mean = round(fit3$beta,4), SD = round(sqrt(diag(fit3$vbeta.ajs)),4), Z = round(fit3$beta/sqrt(diag(fit3$vbeta.ajs)),4), PVal = round(2-2*pnorm(abs(fit3$beta/sqrt(diag(fit3$vbeta.ajs)))),4)) [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. * * * * * * * * * * * * * D I S C L A I M E R * * * * * * * * * * * * * Dit bericht en eventuele bijlagen geven enkel de visie van de schrijver weer en binden het INBO onder geen enkel beding, zolang dit bericht niet bevestigd is door een geldig ondertekend document.
