Summary
Let (X 1,Y 1), (X 2,Y 2),…, (X n,Y n) be i.i.d. as (X, Y). TheY-variate paired with therth orderedX-variateX rn is denoted byY rn and terms the concomitant of therth order statistic. Statistics of the form\(T_n = n^{ - 1} \sum\limits_{i = 1}^n {J\left( {t_{ni} } \right)} Y_{in} \) are considered. The asymptotic normality ofT n is established. The asymptotic results are used to test univariate and bivariate normality, to test independence and linearity ofX andY, and to estimate regression coefficient based on complete and censored samples.
