SAMPLE SIZE AND STRUCTURE FOR MULTILEVEL MODELLING: MONTE CARLO INVESTIGATION FOR THE BALANCED DESIGN

Summary/Abstract: The aim of the study is to examine the robustness of the estimates and standard errors in the case of different structure of the sample and its size. The two-level model with a random intercept, slope and fixed effects, estimated using maximum likelihood, was taken into account. We used Monte Carlo simulation, performed on a sample of the equipotent groups
