error structure in Generalized linear models when y is continuous data and errors not normal...
Lets say I have continuous y and x variable and I run a linear regression:
mdl1<-lm(y ~ x)
A generalised linear model should also give me the same parameters value if I do not specify the error str …

R-squared for linear mixed effects model [duplicate]
I ran linear mixed effects model in R.
model<-lmer(yld ~ rain + (1+rain|state),data=data,REML=FALSE)
Is there any way I can generate an R-squared for the model. … You may want to have a look at Nakagawa & Schielzeth (2013) A general and simple method for obtaining R 2 from generalized linear mixed-effects models. …
