Summarize the Multi-Factor Model

You have now created a two-factor model of the reading comprehension and speeded addition factors. Is that better than a one-factor model? Use the cfa() and summary() functions on your new two-factor model of the HolzingerSwineford1939 dataset to show the fit indices.

Instructions

100 XP
  • Save your model fit as twofactor.fit using the cfa() function.
  • Use the summary() function to view the fitted model.
  • Compare the fit indices from the one-factor model to the updated model.
