Estimation of Parameters of Certain Bivariate Distributions with Equal Coecients of Variation by Concomitants of Order Statistics

Abstract

For a sample of n pairs of observations from Bivariate normal distribution,Morgenstern type bivariate logistic distribution and morgenstern type bivariate exponential distribution , in which the marginal distributions of random variables X and Y have the same coecient of variation c, we derive the best linear unbiased estimator of the parameters associated with the Y variable using concomitants of order statistics.
