Plotting differences in persons' factor scores
Factor loadings aren't the only parameters that differ between EFA and CFA results. Individuals' factor scores also differ when they are calculated from the EFA or CFA parameters. To illustrate this, we'll look at how factor scores for individuals in the bfi_EFA dataset differ when they are calculated from the EFA model versus from the CFA model by examining those scores' density plots.

Istruzioni dell'esercizio
- First, save the scores from the
scoresnamed list element from theEFA_modelobject into a new object. Since this model was created from thebfi_EFAdataset, the factor scores are from that dataset. - Next, use
fscores()to calculate and extract individuals' factor scores using the CFA model object with the samebfi_EFAdataset. - Finally, use the
plot()andlines()functions to graph the densities of the individuals' factor scores on the first factor.
