Model updating functions

Description

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

Usage

addMIs(x, matrices = "all", type = c("normal", "free",
                    "equal"), verbose, analyticFisher = TRUE)

addSEs(x, verbose, approximate_SEs = FALSE)

addfit(x, verbose)

identify(x)

Arguments

`x`	A `psychonetrics` model.
`matrices`	Optional vector of matrices to include in MIs.
`type`	String indicating which modification indices should be updated.
`verbose`	Logical, should messages be printed?
`analyticFisher`	Logical indicating if an analytic Fisher information matrix should be used.
`approximate_SEs`	Logical, should standard errors be approximated? If true, an approximate matrix inverse of the Fischer information is used to obtain the standard errors.
