Abstract:

This study proposes a class of nonparametric tests for the equality of two distributions when samples are collected independently under different, biased sampling schemes. Asymptotic properties are derived using a central limit theorem developed for rejective samples from a finite population. Conditions under which the tests are consistent are given.
