Summarize Political Democracy

Using the PoliticalDemocracy dataset, you created a model that measured political democracy from the 1960s. y1, y2, y3, and y4 measured political and press freedoms, election fairness, and legislature effectiveness. y1 was our indicator variable used to scale the data.

It is also important to examine model variances, which indicate the size of error in estimating manifest or latent variables. Use the summary() function on politics.fit to display the coefficients and variances for the model.

Look at the Estimates column. Which item has the largest error term in the Variances output?
