Usage

test_expected_percent_score(theta, IRT.par, IRT.model = "3PL", IRT.scale = 1.7)

Arguments

theta	A vector of ability values
IRT.par	A matrix of IRT parameters. This should have the columns required by the IRT model of choice.
IRT.model	A vector of character strings that specify the IRT model for each item. This can also be a single value, which will be recycled.
IRT.scale	A vector of scaling parameters used in the IRT models. This can also be a single value, which will be recycled.
is_percent_scale	if TRUE, the expected percent score for the given thetas will be returned, which is the tcc.
