Computation of direct, chain and average (bisector) equating coefficients with
standard errors using Item Response Theory (IRT) methods for dichotomous items
(Battauz (2013) ,
Battauz (2015) ).
Test scoring can be performed by true score equating and observed score equating methods.
DIF detection can be performed using a Wald-type test
(Battauz (2019) ).
The package includes tests to access the stability of the equating transformations
(Battauz(2022) ).
