is the p.d.f. for the ith order statistic for a SRS of size k from the population with p.d.f.
f(x) and c.d.f. F(x). It is this extra structure provided by the judgement ranking and the
independence of the resulting order statistics that enables procedures based on RSS
data to be more efficient than comparable procedures based on a SRS with the same
number of measured observations. On the other hand, these same features also make
the theoretical development of properties for RSS procedures more difficult than for
their SRS counterparts. In the next section, we illustrate both of these aspects via
comparison of the RSS and SRS sample means.
