There is a quite large literature when multivariate endog include discrete or both continuous and discrete random variables. We currently don't have cdf and pdf for copulas that include a discrete ...

A special case of multivariate count data. The general case is often handled with copulas in the literature. The computationally difficult part is that most or almost all methods require numerical ...

Abstract: We address estimation for the multivariate Poisson distribution with second order correlation structure. Existing estimators such as maximum likelihood estimators are too computationally ...

Introduction: As the studies predicting mortality in severe acute respiratory illness (SARI) have inferred associations either from dichotomous outcomes or from time-event models, we identified some ...

It’s one thing to deliver a simple package the next day, or even the same day, but imagine a flatbed of 80-pound bags of concrete, concrete blocks, a bunk of lumber and then throw in some drywall to ...

ABSTRACT: In this paper, a new lifetime class with decreasing failure rate is introduced by compounding truncated binomial distribution with any proper continuous lifetime distribution. The properties ...
