model. |
The IRT model. 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. |
The |
boundaries for parameter generation. See the |
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 \itemseed.The seed for reproducibility. \itemclusters.In the multidimensional case, the clusters to simulate. \itemrepetition.Seed of a single set , this seed does not affect the itempars generated. |
List with model, seed , itempars, and the test simulated. check the documentation of simulateTestMD
for information on the return in the Multidimensional case.
