These data are from the SAS manual and consist of six mental tests for 32 students,
with some missing data. The three x
variables are intended to load on a verbal
factor, and the three y
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.
