...m too big. Also, I'm not sure if I've backtransformed correctly. I've also tried directly calculating the means and CIs, but I'm not sure if the first line below is actually the right variance to use in estimating the CIs. variance<-mm$sigma #IS THIS THE RIGHT VARIANCE? speciessize<- tapply(species, burnagecat1 ,length) speciesmeans<- (tapply(predict(mm, type="response"), burnagecat1 ,mean)) upperci<- exp(log(speciesmeans) + qt(0.95,residdf)*sqrt(variance/speciessize)) lowerci<- exp(log(speciesmeans)- qt(0.95,residdf)*sqrt(variance/speciessize)) re...
