Several sampling designs for assessing agreement between two binary classifications on each of n subjects lead to data arrayed in a four-fold table. Following Kraemer's (1979, Psychometrika 44, ...

Detecting gene–environment interactions with rare variants is critical in dissecting the etiology of common diseases. Interactions with rare haplotype variants (rHTVs) are of particular interest. At ...

Employing a superpopulation model, we derive conditions for which a sampling design of a two-dimensional finite population is optimal in the sense of minimum average variance, when the estimator of ...
