Abstract

This research aimed to study the effectiveness of model selection criteria for multilevel analysis. Both criteria were Akaike’s Information Criteria (AIC) and Bayesian Information Criteria (BIC). The simulation was applied by Monte Carlo technique. The conditions for simulation were 1) populations were having normal distribution; 2) populations were having negative skewness and platykurtic distributions; 3) populations were having positive skewness and leptokurtic distributions; 4) independent variables were divided into two variables for each level; 5) intraclass correlation coefficient were 0.10 and 0.20; and 6) the sample size was divided into four sizes for each level (level 1, the group sizes were 5, 15, 30 and 50; level 2 , the number of groups were 15, 30, 50 and 100.). Each condition was simulated with 1,000 data set. The results revealed that when the number of groups was small, the effectiveness of model selection criteria was considerable low. Whereas the higher the number of groups, the better effectiveness of criteria. Furthermore, when the number of groups was 100, it was found in most cases that the model selection of BIC yielded better effective than AIC when estimating parameter with Restricted Maximum Likelihood (RML). Keywords : Multilevel analysis, Hierarchical Linear Models, AIC, BIC
