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

100 XP

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.
