To whom it may concern, when I was calculating BIC with sem e.g. as follows:
cfa.mod <- cfa(reference.indicators=FALSE, covs=NULL) F1: Sentences, Vocabulary, Sent.Completion, First.Letters, Four.Letter.Words cfa.sem <- sem(cfa.mod, S=Thurstone, N=355) summary(cfa.sem) the BIC value is wrong! For the example it results BIC = 104.5072 Correct with a formula I found in text books: BIC= χ2 + ln(N)[k(k + 1)/2 - df] BIC should be 192.588977895 104.5072 I got, when set k=0 I think there must be a mistake when getting the numbers of parameters.
