Value of N for Computation of Bayesian Information Criterion in Multilevel Modeling
Lorah, Julie Ann
AERA Online Paper Repository, Paper presented at the Annual Meeting of the American Educational Research Association (New York City, NY, Apr 13-17, 2018)
The Bayesian information criterion (BIC) can be useful for model selection within multilevel modeling studies. However, the formula for BIC requires a value for N, which is unclear in multilevel models, since N is observed in at least two levels. The present study uses simulated data to evaluate the rate of false positives and power when using a value for N of: level-1 N, effective N, and level-2 N under various sample size and ICC values. Result indicate that using level-2 N value for computation of BIC results in the highest power while still maintaining reasonably low false positive rates.
