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. |

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 |
