R2noharm.EAP: EAP Factor Score Estimation

In sirt: Supplementary Item Response Theory Models

EAP Factor Score Estimation

Description

This function performs EAP factor score estimation of an item response model estimated with NOHARM.

Usage

R2noharm.EAP(noharmobj, theta.k=seq(-6, 6, len=21), print.output=TRUE)

Arguments

noharmobj	Object of class R2noharm or noharm.sirt
theta.k	Vector of discretized theta values on which the posterior is evaluated. This vector applies to all dimensions.
print.output	An optional logical indicating whether output should be displayed at the console

Value

A list with following entries

person	Data frame of person parameter EAP estimates and their corresponding standard errors
theta	Grid of multidimensional theta values where the posterior is evaluated.
posterior	Individual posterior distribution evaluated at theta
like	Individual likelihood
EAP.rel	EAP reliabilities of all dimensions
probs	Item response probabilities evaluated at theta
