Description: Interpreting the differences between mean scale scores
        across various forms of an assessment can be challenging. This
        difficulty arises from different mappings between raw scores
        and scale scores, complex mathematical relationships,
        adjustments based on judgmental procedures, and diverse
        equating functions applied to different assessment forms. An
        alternative method involves running simulations to explore the
        effect of incrementing raw scores on mean scale scores. The
        'idmact' package provides an implementation of this approach
        based on the algorithm detailed in Schiel (1998)
        <https://www.act.org/content/dam/act/unsecured/documents/ACT_RR98-01.pdf>
        which was developed to help interpret differences between mean
        scale scores on the American College Testing (ACT) assessment.
        The function idmact_subj() within the package offers a
        framework for running simulations on subject-level scores. In
        contrast, the idmact_comp() function provides a framework for
        conducting simulations on composite scores.
