Create a Hierarchical Model

The underlying theory about intelligence states that a general IQ factor predicts performance on the verbal comprehension, working memory, and perceptual organization subfactors. Therefore, you should create a hierarchical model that demonstrates that relationship between the second order latent variable and the first layer of latent variables.

The data has been loaded for you and is called IQdata. You can view the data using head(IQdata).
