simulateTestMD: Simulate test Multidimensional

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)
