|
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 |
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. |
Check the documentation of simulateTestMD
for information
on the return in the Multidimensional case.
List with model, seed, itempars, and the simulated test.
