Description:
A collection of functions for calculating the M2 model fit statistic for diagnostic classification models as described by Liu et al. (2016) . These functions provide multiple sources of information for model fit according to the M2 statistic, including the M2 statistic, the *p* value for that M2 statistic, and the Root Mean Square Error of Approximation based on the M2 statistic.
