Create a matrix of items and their parameters

This matrix already encodes the Q-matrix. It can be useful to save the results for future simulations or further wrangling as a csv.

Usage

build_test_parameters(qmat, ...)

Arguments

qmat

Q-matrix

...

values to use in the different factor levels. i.e. the first number is assumed to be the intercept, then main effects, then two-way interaction and so on.

Value

A matrix of items and their parameters.
