write_mplus_input: Prepare an Mplus Input File

In ItemResponseTrees: IR-Tree Modeling in 'mirt', 'Mplus', or 'TAM'

Description

This is an internal function used by irtree_fit_mplus(). It receives its inputs from the model object and the data set and returns an object of class MplusAutomation::mplusObject.

Usage

write_mplus_input(
  object = NULL,
  pseudoitems = NULL,
  data_file = NULL,
  fsco_file = NULL,
  save_fscores = FALSE,
  quadpts = NULL,
  estimator = NULL,
  link = NULL,
  analysis_list = list()
)

Arguments

object	Object of class irtree_model. See irtree_model for more information.
pseudoitems	Data frame as returned from irtree_recode().
data_file	String, the full file path of the data set.
fsco_file	String, the file name used by Mplus to store the factor scores.
save_fscores	Logical, whether to save FSCORES or not.
quadpts	This is passed to argument 'INTEGRATION' of Mplus. Thus, it may be an integer specifying the number of integration points for the Mplus default of rectangular numerical integration (e.g., quadpts = 15). Or it may be a string, which gives more fine grained control (e.g., quadpts = "MONTECARLO(2000)").
estimator	String, passed to argument 'ESTIMATOR' in Mplus.
link	String, passed to argument 'LINK' in Mplus. Specifies the link function.
analysis_list	Named list of strings passed to Mplus' argument ANALYSIS. See examples below.

Value

A list of of class MplusAutomation::mplusObject
