Differences in estimated factor loadings

The differences between EFAs and CFAs are evident when examining the factor loadings. Not only are the procedures mathematically different, but the number of estimated parameters is also different. By default, EFAs estimate all possible item/factor pairs, while CFAs only estimate specified item/factor relationships. Let's take a look at a few of those estimated loadings and see how they differ.

Which of these loadings represent the EFA and CFA estimates of the relationship between item A1 and the fourth factor (named MR5)?

  • Check out the first five rows of loadings in EFA_model. Remember that the EFA estimates all possible item/factor pairs.
  • Look at the first five loadings in EFA_model. This output only estimates specified item/factor relationships.
