Abstract: | This paper investigates the characterizations of certain discrete distributions within the framework of multivariate additive damage models. The univariate case for such models appoared in an article by N. Krishnaii (1974) and Rao and Rubin (1964). In this paper the survival distriution in specified and it is shown that linearity of the regression of the undamaged part on the damaged part, or the damaged part on the undamaged part leads to the characterizations of independent binomials, independent negative binomials, independent Poissons, multinomial and negative multinomial for the original p-dimensional observation. |
