Tests

These data are from the SAS manual and consist of six mental tests for 32 students,
with some missing data. The three <code>x</code> variables are intended to load on a verbal
factor, and the three <code>y</code> variables on a math factor. The data can be used to
illustrate the estimation of a confirmatory factor analysis model by multinormal full-information
maximum-likelihood in the presence of missing data.

datasets

Functions for fitting general linear structural
equation models (with observed and latent variables) using the RAM approach,
and for fitting structural equations in observed-variable models by two-stage least squares.
