I'm fitting a mixed effects model: fit.1 <- lme(y~x,random=~1|id,data=df) There are two different observations for each id for both x and y. When I use plot(fit.1), there is a strong increasing linear trend in the residuals versus the fitted values (with no outliers). This also happens if I use random=~x|id. Am I specifying something incorrectly? Rick B.

Hello there This is the first time I have used r-help message board so I hope I have got the right address. I am trying to check the residuals of a GLMM model(run using the package lme4). I have been able to check the residiuals of REMLs in lme4 using the following: m1<-lmer(vTotal~Week+fCollar+ (1|fCat), collars) res<-resid(m1) plot(res) qqnorm(res) library(MASS) par(mfrow=c(2,3)) res<-residuals(m1) truehist(res,main="Histogram of Residuals") curve(dnorm(x,mean=mean(res),sd=sd(res)),add=TRUE) qqnor...

...Hmmh. Next. I then looked up the flac formatting guide. I figured that the encoding options used by the majority of applications are just the basic aliases 0-8. What struck me was that the flac formatting guide recommends higher (whatever) blocksizes in case of >48khz HiRez files and also a residiual partition order of 2,2. Since I do not have a lot of background about the internals of the decoder. I can't make much sense out of the advanced features of the formating guide. I'd really appreciate if somebody could tell me what best options to choose for encoding HiRez flacs. My...
