In bgreenwell/mertree: Mixed-Effects Regression Trees for Longitudinal and Clustered Data

Description

Data from Frieman (1991) and Breiman (1996). However, here the errors were generated from a 5-dimensional Gaussian distribution with zero mean and a variance-covariance matrix with 4 along the diagonal and 0.8 in the off-diagonal; see Zhang (1997) for details.

Format

A data frame with 500 rows and 9 variables
