Returns a matrix of profiles and the probability of a correct response for all items.

Source: R/get_probabilities_by_profile.R
get_probabilities_by_profile.Rd

It works by extraxcting the test parameters with get_test_parameters and then passing that to the generate_responses(get_probs=TRUE) with all possible mastery patterns to get the expected probabilities.

Usage

get_probabilities_by_profile(model, marginal_attr = NULL, which_items = NULL)

Arguments

model

A GDINA object

marginal_attr

returns the probabilities marginal on an attribute. It does not consider distribution, is just a mean of the probabiities.

which_items

vector of items to be returnde. If Null it returns all.

Value

a matrix of profiles and the probability of a correct response for all items.
