%description
The goal of 'cvsem' is to provide functions that allow for comparing
Structural Equation Models (SEM) using cross-validation. Users can specify
multiple SEMs using 'lavaan' syntax. 'cvsem' computes the Kullback Leibler
(KL) Divergence between 1) the model implied covariance matrix estimated
from the training data and 2) the sample covariance matrix estimated from
the test data described in Cudeck, Robert & Browne (1983)
<doi:10.18637/jss.v048.i02>. The KL Divergence is computed for each of the
specified SEMs allowing for the models to be compared based on their
prediction errors.
