Achieving the UN Sustainable Development Goals is impossible without addressing fragility, conflict, and violence (FCV), especially as two thirds of the extreme poor are projected to live in such situations by 2030. Conflicts as well as climatic and natural hazards displace millions of people...

In this paper, we introduce a new copula-based dependence order to compare the relative degree of dependence between two pairs of random variables. Relationship of the new order to the existing dependence orders is investigated. In particular, the new ordering is stronger than the partial...

A sufficient condition for comparing convolutions of heterogeneous exponential random variables in terms of right spread order is established. As a consequence, it is shown that a convolution of heterogeneous independent exponential random variables is more skewed than that of homogeneous...

Let X[lambda]1,...,X[lambda]n be independent random variables such that X[lambda]i has exponential distribution with hazard rate [lambda]i, i=1,...,n. It is shown that [summation operator]i=1nX[lambda]i is more dispersed than [summation operator]i=1nX[lambda]i* if ([lambda]1,...,[lambda]n)...
