The manifest model excludes any latent variables or processes. For RAM and LISREL models, the manifest model contains only the manifest variables with free means, covariance, and thresholds.

The Jacobian is estimated by the central finite difference.
If the standardize argument is TRUE, then the Jacobian is for the standardized model.
For Normal expectations the standardized manifest model has the covariances returned as correlations, the variances returned as ones, the means returned as zeros, and the thresholds are returned as z-scores.
For the thresholds the z-scores are computed by using the model-implied means and variances.
