Generalized Discrimination Index [PDF]
<p style="text-align:justify">Kelley’s Discrimination Index (DI) is a simple and robust, classical non-parametric short-cut to estimate the item discrimination power (IDP) in the practical educational settings. Unlike item–total correlation, DI can reach the ultimate values of +1 and ‒1, and it is stable against the outliers.

To what extent are item discrimination values realistic? A new index for two-dimensional structures
Most researchers investigate the corrected item-total correlation of items when analyzing item discrimination in multi-dimensional structures under the Classical Test Theory, which might lead to underestimating item discrimination, thereby removing items

Dimension-corrected discrimination index
Abstract The Discrimination Index ( DI ) or upper-lower index is a simple and robust, classical non-parametric shortcut to evaluate the item discrimination power or item validation in the practical testing settings. Empirical results show that the DI

Evaluation of competing risks prediction models using polytomous discrimination index. [PDF]
For competing risks data, it is often important to predict a patient's outcome status at a clinically meaningful time point after incorporating the informative censoring due to competing risks. This can be done by adopting a regression model that relates
