The Bayes information criterion (Schwarz, 1978; Raftery, 1995) is given by the formula,
.
Amos 4 used the formula (Raftery, 1993),
.
In comparison to AIC, BCC and CAIC, BIC assigns a greater penalty to model complexity, and so has a greater tendency to pick parsimonious models. BIC is reported only for the case of a single group where means and intercepts are not explicit model parameters.
