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.

Value

An object of the class psychonetrics (psychonetrics-class)
