simulateTest: Simulates a test

In IRTpp: Estimating IRT Parameters using the IRT Methodology

Description

Simulates a test according to a IRT Model.

Usage

simulateTest(model = "3PL", items = 10, latentTraits = NULL,
  individuals = 1000, boundaries = NULL, dims = 1, itempars = NULL,
  verbose = F, threshold = 0, seed = 500L, clusters = NULL,
  repetition = 1)

Arguments

model	The IRT model. "1PL","2PL" or "3PL". In Multidimensional is "3PL".
items	The items to simulate in the test.
latentTraits	The latentTraits in the UIRT case.
individuals	The individuals to simulate in the test.
boundaries	The boundaries for parameter generation. See the simulateItemParameters documentation for help.
dims	The dimensionality of the test.
itempars	A list with teh parameters of the items if provided.
verbose	Verbosibity for more information about the process, use when simulating long tests.
threshold	A boundary for the percent of answered questions to a test. i.e. 0.05 indicates the individuals will answer maximum the 95% of the questions and minimum the 5% of the questions. UIRT only.
seed	Desired seed to use in test generation. If null, a seed based on the current time will be used.
clusters	Used for MD test generation.
repetition	Used for MD test generation.

Details

Check the documentation of simulateTestMD for information on the return in the Multidimensional case.

Value

List with model, seed, itempars, and the simulated test.
