personparm: calculate person (incidental) parameters

In GDINA: The Generalized DINA Model Framework

calculate person (incidental) parameters

Description

Function to calculate various person attribute parameters, including "EAP", "MAP", and "MLE", for EAP, MAP and MLE estimates of attribute patterns (see Huebner & Wang, 2011), "mp" for marginal mastery probabilities, and "HO" for higher-order ability estimates if a higher-order model is fitted. See GDINA for examples.

Usage

personparm(object, what = c("EAP", "MAP", "MLE", "mp", "HO"), digits = 4, ...)

Arguments

object	estimated GDINA object returned from GDINA
what	what to extract; It can be "EAP", "MAP", and "MLE", for EAP, MAP and MLE estimates of attribute patterns, and "mp" for marginal mastery probabilities, and "HO" for higher-order ability estimates if a higher-order model is fitted.
digits	number of decimal places.
...	additional arguments
