Using a Monte Carlo simulation, we investigated these conditions and tested alternative estimators and degrees of freedom (df) adjustments to assess how well they could ameliorate the issues related to the use of the traditional CRSE (CR1) estimator using both continuous and dichotomous predictors. Findings showed that the bias-reduced linearization estimator (CR2) and the jackknife estimator (CR3) together with df adjustments were generally effective at maintaining Type I error rates for most of the conditions tested. Results also indicated that the CR1 when paired with df based on the effective cluster size was also acceptable.

This article introduces a new coefficient, weighted Lambda, which allows for the inclusion of varying weights assigned to disagreements. Unlike traditional methods, this coefficient does not assume random assignment and does not adjust for chance agreement or disagreement. Instead, it modifies the observed percentage of agreement while taking into account the anticipated impact of prevalence-agreement effects. The study also outlines techniques for estimating sampling standard errors, conducting hypothesis tests, and constructing confidence intervals for weighted Lambda.

Stepwise and LASSO methods were largely ineffective at eliminating problematic variables under the studied conditions.

Like Cohen's Kappa, it adjusts the observed proportion of agreement to account for agreement expected by chance. However, over time, several paradoxes and interpretative challenges have been identified, largely stemming from the assumption of random chance agreement and the sensitivity of the coefficient to the number of raters. Interpreting Fleiss's Kappa can be particularly difficult due to its dependence on the distribution of categories and prevalence patterns. This paper argues that a portion of the observed agreement may be better explained by the interaction between category prevalence and inherent category characteristics, such as ambiguity, appeal, or social desirability, rather than by chance alone. By shifting away from the assumption of random rater assignment, the paper introduces a novel agreement coefficient that adjusts for the expected agreement by accounting for category prevalence, providing a more accurate measure of interrater reliability in the presence of imbalanced category distributions.

Four equating methods (identity, IRT true-score, linear, equipercentile) were compared using normalized RMSE and %Bias.
