emxFactorModel: Create a factor model

In EasyMx: Easy Model-Builder Functions for 'OpenMx'

Create a factor model

Description

This function creates a factor model as an MxModel object.

Usage

emxFactorModel(model, data, name, run=FALSE, identification, use, ordinal,
    ..., parameterization=c("lisrel", "ifa"), weight = as.character(NA))
emxModelFactor(model, data, name, run=FALSE, identification, use, ordinal,
    ..., parameterization=c("lisrel", "ifa"), weight = as.character(NA))

Arguments

model	named list. Gives the factor loading pattern. See Details.
data	data used for the model
name	character. Optional name of the model created.
run	logical. Whether to run the model before returning.
identification	Not yet implemented. How the model is identified. Currently ignored.
use	character vector. The names of the variables to use.
ordinal	character vector. The names of the ordinal variables.
...	Force later arguments to be named. ... is ignored.
parameterization	character. Whether to specify the model as a LISREL SEM or as an Item Factor Analysis
weight	character. Name of the data column used for sample weights.

Details

The model argument must be a named list. The names of the list give the names of the latent variables. Each list element gives the names of the variables that load onto that latent variable. This may sound complicated, but the example below makes this more clear. It is intended to be visually intuitive.

Value

An MxModel.

# Example
require(EasyMx)
data(myFADataRaw)
xmap <- list(F1=paste0('x', 1:6), F2=paste0('y', 1:3), F3=paste0('z', 1:3))
## Not run: 
mod <- emxFactorModel(xmap, data=myFADataRaw, run=TRUE)

## End(Not run)
