# 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.
