I'm doing hierarchical regression analyses with missing data in Mplus.
To say something about the statistical significance of the change in the amount of variance explained, R2-change (R2-model2 minus R2-model1), between two regression analyses I'm calculating the F-change statistic. Therefore I need to know the degrees of freedom (df) for the regression model and the residual df. Without missing data no problem.
But how can I make Mplus compute these degrees of freedom in a regression analysis when I'm using FIML or when I'm using Multiple Imputation (TYPE=imputation)?
