R2noharm.EAP

EAP Factor Score Estimation

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

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

`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

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`
