NOTE: The estimates 1.575, 1.719 and 1.657 are covariances. The values given in the StdYX column are correlations (which are standardized covariances). The values in the Estimates (covariances) and StdYX (correlations) columns are often the same because we often constrain the variances of the factors to equal 1. In this case, we did not, so we get both the covariance and the correlation estimates.
