EFA model iteration

Even if your data and your theory suggest otherwise, it's a good idea to explore what happens when you include more or fewer factors in your EFA. For purposes of brevity, we will experiment with changes to the number of factors on the brand_rep_8 data frame, but in reality you might also check brand_rep_9 to check for the effect of one_of_a_kind loadings on overall fit.

Let's see how going up to 4 and down to 2 factors affects our EFA model fit. psych and dplyr have been loaded into your environment.
