On strong unimodality of multivariate discrete distributions
A discrete function f defined on Zn is said to be logconcave if f(λx+(1− λ)y) ≥ [f(x)]λ[f(y)]1−λ for x, y, λx + (1− λ)y ∈ Zn. A more restrictive notion is strong unimodality. Following Barndorff-Nielsen (1973) a discrete function p(z), z ∈ Zn is called strongly unimodal if there exists a convex function f(x), x ∈ Rn such that f(x) = − log p(x), if x ∈ Zn. In this paper sufficient conditions are...
متن کاملClassification and properties of acyclic discrete phase-type distributions based on geometric and shifted geometric distributions
Acyclic phase-type distributions form a versatile model, serving as approximations to many probability distributions in various circumstances. They exhibit special properties and characteristics that usually make their applications attractive. Compared to acyclic continuous phase-type (ACPH) distributions, acyclic discrete phase-type (ADPH) distributions and their subclasses (ADPH family) have ...
متن کاملA note on inconsistent families of discrete multivariate distributions
We construct a d-dimensional discrete multivariate distribution for which any proper subset of its components belongs to a specific family of distributions. However, the joint d-dimensional distribution fails to belong to that family and in other words, it is ‘inconsistent’ with the distribution of these subsets. We also address preservation of this ‘inconsistency’ property for the symmetric Bi...
متن کاملOn discrete a-unimodal and a-monotone distributions
Unimodality is one of the building structures of distributions that like skewness, kurtosis and symmetry is visible in the shape of a function. Comparing two different distributions, can be a very difficult task. But if both the distributions are of the same types, for example both are unimodal, for comparison we may just compare the modes, dispersions and skewness. So, the concept of unimodali...
