simulate_polytomous: Polytomous data simulation

In SICSresearch/LatentREGpp: Item Response Theory Implemented in R and Cpp

Description

This function generates dichotomous test of an specified dimension and size. The items per dimension are specified in the size.cluster vector, and the individuals are specified in sample.size. The amout of categories of each item is determined with ncatgs.

Usage

simulate_polytomous(dim.data = 1, sample.size = 1000,
  size.cluster = c(20), ncatgs = rep(4, 20), seed_data = 5000L,
  model = "2PL")

Arguments

dim.data	Data dimension
sample.size	Size of the population that will be simulated
size.cluster	Vector containing the number of items by dimension
ncatgs	Vector containing the number of categories for each item
seed_data	Seed for simulation
model	the model used to generate the test. It can have values of "1PL", "2PL" or "3PL".

Value

list with the simulated data, the information of the item parameters and the individual parameters
