With ML estimator how are RMSEA, and BIC computed for CFA with twolevel, threelevel and crossclassified models? 1. RMSEA with a grouping variable: RMSEA = sqrt((chisquare/(n*d))  (1/n))*sqrt(g) a. what is n = nclusters or n = total level1 observations? b. What is g with a within level or betweenlevel grouping variable? 2. BIC = 2LL + np*log(n) a. what is n = nclusters or n = total level1 observations? b. What about missing data? 


RMSEA is not computed with crossclassified models in Mplus 1a. Find in the output "Number of observations" i.e. n = total level1 observations 1b. G is a betweenlevel grouping variable (always) and is just the number of groups. 2a. n = total level1 observations, find in the output "Number of observations" 2b. If an observation has missing values on all dependent variables, it is not counted in n.
