cbm.wpm.sort: Sort the given items by their value to the simulee according...

In yuehmeir2/CATSimulator: Library for Simulation of Adaptive Item Selection

Description

The 'wpm' algorithm uses a composite sort key to order the items: * The primary key is the progress of each constraint on the item, relative to its lower/upper bound * The secondary key is the information value of each item

Usage

cbm.wpm.sort(eligibleModuleIndices, simuleeOut, simulation)

Arguments

eligibleModuleIndices	A vector of itempool indices eligible for selection.
simuleeOut	A tibble containing the in-progress simulee test output.
simulation	An object defining the test that is being run.

Value

The eligibleModuleIndices, sorted by their value to the simulee.

Examples

  simulation = initSimulation(readRDS(system.file("example/passage-adaptive-wpm.rds", package = "CATSimulator")))
  simuleeOut = initSimulee(generateSimuleesByTrueTheta(-2, 10001), simulation)
  eligibleModuleIndices = 1:nrow(simulation$modules)
  balancedModuleIndices = cbm.wpm.sort(eligibleModuleIndices, simuleeOut, simulation)
