Simulate-test-Multidimensional: Simulate test Multidimensional

In SICSresearch/IRTpp_old: Estimating IRT parameters using the IRT Methodology

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.
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.
