EAP Factor Score Estimation — R2noharm.EAP • sirt

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
