Description Usage Arguments Value See Also Examples

Simulates a test according to a model and saves it to files, can be slow due to disk usage.

simulateTest.file(model = "2PL", items = 10, individuals = 1000,
  reps = 1, dims = 1, filename = "test", directory = NULL,
  boundaries = NULL, itempars = NULL, latentTraits = NULL, seed = NULL,
  verbose = F, threshold = 0)

`model`	A string with the model to simulate, please refer to the model documentation in irtpp documentation.
`items`	the number of items to simulate
`individuals`	the number of individuals to simulate
`reps`	The number of tests to generate with this settings
`dims`	Optional. The number of dimensions to simulate in the test if the model is multidimensional TODO (Untested in multidimensional, please do not use this parameter for now)
`filename`	A name to give the tests.
`directory`	The directory to output the tests
`boundaries`	Optional. The kind of boundaries that are specified for the parameters.
`itempars`	Optional. Item parameters to be used in the simulation. When the parameters are not generated, the item parameters must be specified.
`latentTraits`	A set of latent traits to set them for the individuals
`seed`	Optional. Seed to use to generate all the data
`verbose`	Optional. If true, output is made to know the status of the algorithm
`threshold`	The threshold that indicates the boundaries on the individual scores (to avoid nearly perfect or nearly )
