How to deal with multicollinearity in mixed models (with lmer)?
...7.html" which
states that if not for interpretation but just for prediction,
multicollinearity does not matter much. However, I am using mixed model to
interpret something, so I am wondering if there is a suitable method to deal
with this problem in lmer.
My model is:
model2<-lmer(sur_prop~(kidc+I(kidc^2)+I(kidc^3))*(byear_c+I(byear_c^2)
+I(byear_c^3)+I(byear_c^4))+(byear_c|Studyparish),family=binomial)
This is the maximum model and I have not begun to simplify it. The model is
used to interpret the pattern how a mother's cohort year and total number of
children will affect average sur...
