logLik: Log-likelihood of a RE-EM tree

Description

This returns the log-likelihood of the effects model of a RE-EM tree. This is the log-likelihood of the random effects model estimated in the RE-EM tree. (The regression tree is not associated with a log-likelihood.)

Usage

logLik.REEMtree(object,...)

Arguments

object

an object of class REEMtree
