Psychometrika, 2015, vol. 80, issue 3, 619-624

Abstract: In this rejoinder we discuss the following aspects of our approach to model discrepancy: the interpretations of the two populations and adventitious error, the choice of inverse Wishart distribution, the perceived danger of justifying a model with bad fit, the relationship among our new approach, Chen’s (J R Stat Soc Ser B, 41:235–248, 1979 ) approach and the existing RMSEA-based approach, and the Pitman drift assumption.
