Factor scores & regression

Factor scores can be extracted from a structural equation model and used as inputs in other models, with some loss of information and stability. Previously, we used lavaan to regress spending on our three dimensions of brand quality. What happens if we take the factor scores from the brand quality dimensions, then regress spending on them outside of lavaan? Let's find out!

dplyr and lavaan have been loaded into your environment.

A scaled data frame containing three independent variables, factors F1, F2, F3 and the dependent variable, spend, has been loaded as bq_fs_spend. Build this regression using lm() and assign the results to bq_fs_reg.
