The R packages ‘miceadds’ and ‘mice’ were used to compute pooled F values and significance levels for each variable in the model. Denominator df (error) varied with each calculation and is approximated by ∞ (large number of degrees of freedom). SS, MS, and partial η2 are averaged over the ten imputed data sets.
