IRT.WrightMap: Wright Map for Item Response Models by Using the 'WrightMap'...

Description Usage Arguments Details Value Author(s) See Also Examples

View source: R/IRT.WrightMap.R

Description

This function creates a Wright map and works as a wrapper to the wrightMap function in the WrightMap package. The arguments thetas and thresholds are automatically generated from fitted objects in TAM.

Usage

## S3 method for class 'tam.mml'
IRT.WrightMap(object, prob.lvl=.5, type="PV", ...)

## S3 method for class 'tamaan'
IRT.WrightMap(object, prob.lvl=.5, type="PV", ...)

Arguments

object

Object of class tam.mml or class tamaan

prob.lvl

Requested probability level of thresholds.

type

Type of person parameter estimate. "PV" (plausible values), "WLE" (weighted likelihood estimates) and "Pop" (population trait distribution) can be specified.

...

Further arguments to be passed in the wrightMap (WrightMap) function. See Examples.

Details

A Wright map is only created for models with an assumed normal distribution. Hence, not for all models of the tamaan functions Wright maps are created.

Value

A Wright map generated by the WrightMap package.

Author(s)

The IRT.WrightMap function is based on the WrightMap::wrightMap function in the WrightMap package.
