IRT.drawPV: Function for Drawing Plausible Values

Description

This function draws plausible values of a continuous latent variable based on a fitted object for which the IRT.posterior (CDM) method is defined.

Usage

Arguments

object

Object for which the method IRT.posterior (CDM) does exist.

NPV

Number of plausible values to be drawn.

Value

• Matrix with plausible values
