1. For each cut score, the reference category of the dependent variable PL in science is the consecutive cut score. Mplus does not provide Pseudo R2 for multinomial logistic regressions. The Nagelkerke R2 for the four models calculating manifest regressions in SPSS for all five PVs are: $$R^{2}_{{{\text{Model}}\;{\text{A}}}}$$ = 0.17–0.20, $$R^{2}_{{{\text{Model}}\;{\text{B}}}}$$ = 0.21–0.23, $$R^{2}_{{{\text{Model}}\;{\text{C}}}}$$ = 0.21–0.23, $$R^{2}_{{{\text{Model}}\;{\text{D}}}}$$ = 0.22–0.24. OR = odds ratio, SElog odds = standard error of the log odds
