Build Political Democracy Model
You can now expand your model specification skills to a new dataset. Create a model of Political Democracy ratings from 1960 using the PoliticalDemocracy dataset. This dataset includes ratings of politics in developing countries from the 1960s.
Variables y1, y2, y3, and y4 measure freedom of the press, freedom of political opposition, election fairness, and effectiveness of the legislature. You should create a model with one latent variable, named poldemo60, and four manifest variables.
