SimulateItemParameters: Simulates item parameters for UIRT models.

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

Description

Simulates item parameters depending on a model

Usage

simulateItemParameters(items, model, dims = 1, boundaries = NULL)

Arguments

items	Number of items to generate
model	A string with the model to simulate, please refer to the model documentation in irtpp documentation.
dims	Optional. The number of dimensions to simulate in the test if the model is multidimensional
boundaries	Optional. The kind of boundaries that are specified for the parameters.

Value

A list containing the values of the parameters simulated according to the chosen model.
