simplef

theta

an item design matrix that is of size response categories (k) by three. The three columns are:
* column one is scoring values, usually from 0 to k.
* column two is the delta dot parameter repeated k times
* column three is the tau parameter where for k = 1, tau = 0, and for k &gt; 2, subsequent entries are deviations from delta dot.

params

returns expected score at a given value of theta.

internal

Extends 'ACER ConQuest' through a family of functions
designed to improve graphical outputs and help with advanced analysis
(e.g., differential item functioning). Allows R users to call
'ACER ConQuest' from within R and read 'ACER ConQuest' System Files
(generated by the command 'put'). Requires 'ACER ConQuest' version
5.19.5 or later. A demonstration version can be downloaded from
<https://shop.acer.org/acer-conquest-5.html>.
