These functions update a psychonetrics model. Typically they are not required.

An object of the class psychonetrics (psychonetrics-class)
A psychonetrics model.
Optional vector of matrices to include in MIs.
String indicating which modification indices should be updated.
Logical, should messages be printed?
Logical indicating if an analytic Fisher information matrix should be used.
Logical, should standard errors be approximated? If true, an approximate matrix inverse of the Fischer information is used to obtain the standard errors.
