The effects of correlation between class on parameter estimates in small group sizes of multilevel data

Multilevel analysis is usually performed on hierarchical data consisting of two or more levels. The highest level is the cluster level and the lowest level is individual level. The variation between levels is known as the intraclass correlation, ρ. This study discusses the effects of the intraclass...
