Testing for Equality Between Two Copulas
We develop a test of equality between two dependence structures estimated through empirical copulas. We provide inference for independent or paired samples....

A weighted spatial median is proposed for the multivariate location problem with cluster correlated data. Its limiting distribution is derived under mild co...

We investigate the common practice of estimating the dependence structure between CDS prices on multi-name credit instruments by the dependence structure of ...

Colour image quantization is a data compression technique that reduces the total set of colours in an image to a representative subset. This problem is expr...

This paper proposes new tests of randomness for innovations of a large class of time series models. These tests are based on functionals of empirical proces...

Past studies have shown the unstability of unstructured peer-to-peer networks, in particular Gnutella. Because of this unstability, queries in these network...

We consider the problem of orienting the edges of a graph so that the length of a longest path in the resulting digraph is minimum. As shown by Gallai, Roy ...

The aim of this paper is to present efficient algorithms for the detection of multiple targets in noisy images of a finite region. The algorithms are based ...
