mleCalc

a data frame made up of rows of vectors of item responses, one for each case.

responses

a list of item designs (each used in a call to `simplef`). Must be of same length as `responses`.

itemParams

optional arguments, e.g., perfAdj.

returns the MLE for each case and asymptotic variance given a _fixed_ set of item parameters.
 This is done by finding the root of the distance between the observed and expected score at theta.
 That is, the location where O-E = 0.

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>.
