Returns a matrix item-parameters from model — get_test

This extracts a model's item parameters as a matrix If pretty_print is true, then it also prints a pretty version of the table.

Usage

get_test_parameters(model, complete = TRUE, pretty_print = TRUE, digits = 2)

model: a GDINA object. It has to be logit link function.
complete: If the model only estimated some parameters this will not show in the table. So, for example, the ACDM model will only return main effects. If true this returns the complete table and fills the corresponding parameters with 0. This also ensures a consistent order of the parameters.
pretty_print: boolean. If true it prints a pretty table. It returns a data frame silently.
digits: rounding digits when printing. The return is not approximated.
