Build Text Speed Model
Let's practice defining models. Remember to name your latent variables with a name that is not in your current dataset. However, manifest variables should be column names from your dataset.
Use the HolzingerSwineford1939
dataset to create a new model of textual speed with the variables x4
, x5
, and x6
, which represent reading comprehension and understanding word meaning. x7
, x8
, and x9
represent speed counting and addition. The model will have one latent variable that predicts scores on these six manifest variables.
