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.

  • First, save the scores from the scores named list element from the EFA_model object into a new object. Since this model was created from the bfi_EFA dataset, the factor scores are from that dataset.
  • Next, use fscores() to calculate and extract individuals' factor scores using the CFA model object with the same bfi_EFA dataset.
  • Finally, use the plot() and lines() functions to graph the densities of the individuals' factor scores on the first factor.
