extracting values from lmer
Hi Kevin, Maybe there is a better way (a function) , but you can use: yourmodel at deviance["sigmaREML"] it returns the residual std. dev. : 0.13636 (in case of the default setting for lmer() , i.e. REML=TRUE) More generally, " str(yourmodel) " gives useful informations .

I am trying to extract the residual variance from the lmer function in the package lme4. For example, I have the following response from lmer: Random effects:
Groups Name Variance Std.Dev. Cell.line:DNA.extract (Intercept) 0.130554 0.36132 Residual *0.018595* 0.13636
I want to extract 0.018595 from this output. VarCorr allows me to extract the variance 0.130554, but I want to be able to extract the Residual variance and I don't see a function that does this in lme4. Any ideas? [[alternative HTML version deleted]]
