An Association Test for Multiple Traits Based on the Generalized Kendall’s Tau [PDF]
In many genetics studies, especially in the investigation of mental illness and behavioral disorders, it is common for researchers to collect multiple phenotypes to characterize the complex disease of interest. It may be advantageous to analyze those phenotypic measurements simultaneously if they share a similar genetic mechanism.

Multiple Ordinal Correlation Based on Kendall’s Tau Measure: A Proposal
The joint analysis of various ordinal variables is necessary in many experimental studies within research fields such as sociology and psychology. Therefore, the necessary measures of multiple ordinal dependence must be easy to interpret and facilitate ...

Investigator’s Global Assessment of Chronic Prurigo: A New Instrument for Use in Clinical Trials
Chronic prurigo is a pruritic disease characterized by the development of pruriginous lesions due to scratching. The number of lesions is representative of the stage of the disease, while the presence of excoriations reflects the scratching activity. Aim
