confint.mplus.model: Return confidence intervals for an mplus.model object

Description

This is a method for returning the confidence of an mplus.model object. It works directly on an object stored from readModels such as: object <- readModels("/path/to/model/model.out").

Method that calls confint.mplus.model. See further documentation there.

Usage

# S3 method for mplus.model
confint(
  object,
  parm,
  level = 0.95,
  type = c("un", "std", "stdy", "stdyx"),
  params = c("regression", "loading", "undirected", "expectation", "variability", "new"),
  ...
)
# S3 method for mplusObject
confint(object, ...)

Value

A data frame of class ‘mplus.model.cis’, or in the case of multiple group models, a list of class ‘mplus.model.cis’, where each element of the list is a data frame of class ‘mplus.model.cis’.

Arguments

object

An object of class mplusObject

parm

Included as all confint() methods must include it. Not used currently for Mplus.

level

A numeric vector indicating the level of confidence interval to extract. Options are .95, .90, or .99 as those are all Mplus provides.

type

A character vector indicating the type of confidence intervals to return. One of “un”, “std”, “stdy”, or “stdyx”.

params

A character vector indicating what type of parameters to extract. Any combination of “regression”, “loading”, “undirected”, “expectation”, “variability”, and “new”. A single one can be passed or multiple. By default, all are used and all parameters are returned.

...

Additional arguments to pass on (not currently used)
