Comparing Expert and Trainee Assessments Using Regression Techniques

Abstract

Models are constructed to compare trainee and expert assessment strategies. These models detect trainee differences in assessment in terms of location and scale, and detect the presence of bias towards particular groups of a population. Although the assessment may be evaluated by means of hypothesis tests, emphasis is placed upon the use of a criterion (Mallows, 1973). The use of these procedures in assessment training programs is demonstrated in an application.
