In conquestr: An R Package to Extend 'ACER ConQuest'

Generate item responses for all cases and items (C++ backend of genResponses)

Description

Loops over cases (outer) and items (inner), drawing one uniform deviate per non-missing case-item pair, in the same order as the original R implementation.

Usage

genResponsesCpp(
  abilities,
  itemParams,
  itemDim,
  perturbItems,
  perturbIdx,
  perturbCase
)

Arguments

abilities	A cases by dimensions NumericMatrix.
itemParams	A list of item matrices (see simplep).
itemDim	An IntegerVector (1-based), the ability column for each item.
perturbItems	A list of perturbed item matrices.
perturbIdx	An IntegerVector of length length(itemParams); 0 if the item is not perturbed, otherwise a 1-based index into perturbItems.
perturbCase	A cases by length(perturbItems) LogicalMatrix; TRUE where the case receives the perturbed item.

Value

A cases by items NumericMatrix of responses.
