BlisClass-class: BLIS S4 class

In ShinyItemAnalysis: Test and Item Analysis via Shiny

BLIS S4 class

Description

Extends mirt's SingleGroupClass directly (meaning all mirt methods that work with that class will work with BlisClass too; make sure mirt is loaded).

Details

The purpose of the class is to have a custom coef method (see coef,BlisClass-method) dispatched and the original levels with correct response (as a key attribute) stored in the resulting fitted model.

Slots

orig_levels

list of original levels with logical attribute key, which stores the information on which response (level) has been considered as correct. Note that levels not used in the original data are dropped.
