simulateTestMD: Simulate test Multidimensional

In SICSresearch/IRTpp: Estimating IRT Parameters using the IRT Methodology

Description

Simlates a multidimensional test

Usage

simulateTestMD(items = 10, individuals = 1000, dims = 3, clusters = 4,
  seed = 10, z = NULL, repetition = 1)

Arguments

items	The items to simulate
individuals	The individuals that answer the test.
dims	The dimensions of the test.
clusters	The cluster number to simulate
seed	A seed for reproducibility.
z	A parameter list to feed the function.
repetition	A number of repetition to simulate with the same item parameters different tests.

Value

This function returns the following data in a named list :

• test : The simulated test

• z : A IRT parameter list.

• clusters : The list of cluster sizes per cluster.

• direction : The directions in the dimensions for each cluster.

• clustinit : The principal item of each cluster

• clusterlist : The range list of the clusters.

Examples

# simulateTestMD(items = 10, individuals = 1000, dims = 3, clusters = 4,
# seed = 10, z = NULL, repetition = 1)
