Two Simple Models for Rater Effects

Key Points

• The aim is to estimate rater effects in rating designs with overlapping rater pairs using two models.
• Consideration of two models: additive and nonlinear.
• Examination of rater effects through analytical estimates.
• Illustration of the models with empirical data.
• The additive model effectively captures rater effects in overlapping designs.
• The nonlinear model provides alternative insights into rater ratings.
• Illustrated data supports the effectiveness of both models.
