How to estimate variance components with lmer for models with random effects and compare them with lme results
...mily, method="REML") However, in some cases, lme does not converge, hence I used lmer from the lme4 package: lmer(Trait~1+(Treatment*Source|Family),data=DATA) Where I extract the variances from the model using the summary function: model<-lmer(Trait~1+(Treatment*Source|Family),data=regrexpdat) results<-model at REmat variances<-results[,3] I get the same values as with the VarCorr function. I use then these values to calculate the actual percentage of variation taking the sum as the total variation. Where I am struggling is with the interpretation of the results from the initial...
