Wishartness and independence of matrix quadratic forms in a normal random matrix

open access: yes
Let Y be an nxp multivariate normal random matrix with general covariance [Sigma]Y. The general covariance [Sigma]Y of Y means that the collection of all np elements in Y has an arbitrary npxnp covariance matrix. A set of general, succinct and verifiable

Bivariate generalized exponential distribution

open access: yes
Recently it has been observed that the generalized exponential distribution can be used quite effectively to analyze lifetime data in one dimension. The main aim of this paper is to define a bivariate generalized exponential distribution so that the ...

A class of bivariate exponential distributions

open access: yes
We introduce a class of absolutely continuous bivariate exponential distributions, generated from quadratic forms of standard multivariate normal variates.

On Stein's lemma, dependent covariates and functional monotonicity in multi-dimensional modeling

open access: yes
Tracking the correct directions of monotonicity in multi-dimensional modeling plays an important role in interpreting functional associations. In the presence of multiple predictors, we provide empirical evidence that the observed monotone directions via

Canonical representation of conditionally specified multivariate discrete distributions

open access: yes
Most work on conditionally specified distributions has focused on approaches that operate on the probability space, and the constraints on the probability space often make the study of their properties challenging.
