Exercise

Build a Multi-Factor Model

Another way to improve our text-speed model would be to create a two-factor model with text and speed as latent variables, rather than split the model into two one-factor models. In this exercise, write the model specification code for a two-factor model.

If you want to view the dataset to see the columns, you can use head(HolzingerSwineford1939).

Instructions

Name your model twofactor.model.
Use x4, x5, and x6 to create a text latent variable.
Use x7, x8, and x9 to create a speed latent variable.
