mixed quantile regression
Dear all, I am looking for any (introductory) paper, and ideally a R package, dealing with quantile regression within a linear mixed modelling framework. I know the "quantreg" package, but it can't deal with random effects. I need to apply quantile regression within blocks (a random factor nested within a fixed one) and I have no idea how to deal with this problem. Any help is welcome !
