Try to fit a longitudinal dataset using generalized mixed effects models via the R function gamm() as follows:
library(mgcv) gamm0.fit<- gamm(y ~ x+s(z,bs="cr"), random=list( x=~1, s(z,bs="cr")=~1 ), family = binomial, data =raw) the data is given by raw=(id, y,x,z). It doesn't work. If you can tell me how to fix this problem, it will be appreciated.
