Abstract: QQ-plots are extremely useful in univariate data analysis. In this article, Koltchinskii (1997) and Chaudhuri’s (1996) definition of multivariate quantile is used to develop analogous plots for bivariate data. Bivariate qq-plots are exhibited for comparing a sample to a given population distribution (the bivariate normal), and for comparing two or more bivariate samples. The plots are...
In this paper, we present a class of multivariate copulas whose two-dimensional marginals belong to the family of bivariate Fréchet copulas. The coordinates of a random vector distributed as one of these copulas are conditionally independent.Weprove that thesemultivariate copulas are uniquely determined by their two-dimensional marginal copulas. Some other properties for thesemultivariate copul...
In this paper, we estimate the reliability of a parallel system with two components. We assume that the strengths of these components follow bivariate pareto (BVP) distribution proposed by Veenus and Nair(1994). These two components are subjected to either two independent stresses or common stress which are ( is ) independent of strengths of two components. We assume that the distribution of st...
