Iterated failure rate monotonicity and ordering relations within Gamma and Weibull distributions
Idir Arab, Paulo Eduardo Oliveira
Stochastic ordering of distributions of random variables may be defined by the relative convexity of the tail functions. This has been extended to higher order stochastic orderings…

Asymptotic results for certain weak dependent random variables
Idir Arab, Paulo Eduardo Oliveira
We consider a special class of weak dependent random variables with control on covariances of Lipschitz transformations. This class includes, but is not limited to, positively, neg…
