psychonetrics_update {psychonetrics}

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)
