Tree-based methods are frequently used in studies with censored survival time. Their structure and ease of interpretability make them useful to identify p...

In this paper, we consider the problem of constructing confidence intervals for a population median when the underlying population is discrete. We describe ...

In this paper, we consider testing the location parameter with multilevel (or hierarchical) data. A general family of weighted test statistics are introduced...

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

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

Multivariate one-sample location problem for clustered data is considered from a nonparametric viewpoint. We develop the spatial median and its affine equiv...

We consider the multivariate location problem with cluster correlated data. A family of multivariate weighted sign tests are introduced for which observatio...

This paper presents and assesses a procedure to estimate conventional parameters characterizing fluctuations at the business cycle frequency, when the econ...

In this paper, we study the Pitman asymptotic efficiencies of the sign and the Wilcoxon signed-rank tests for cluster correlated data. A general expression ...

In this paper, we adapt the Wilcoxon signed-rank test to the case of cluster correlated data. A simple modification of the estimator of the asymptotic vari...

In this paper, we perform an empirical comparison of the classification error of several ensemble methods based on classification trees. This comparison is b...

We consider the problem of testing the hypothesis that a multivariate location vector is in the positive orthant. A conditionally distribution-free sign te...

A multivariate location model for cluster correlated observations is presented. An affine-invariant multivariate sign test for testing location is proposed...

The one-sided one sample problem with bivariate data is considered. A conditionally distribution-free sign test is proposed for that problem. This test is ...
