In this work, we present the results of several simulations on main-effect factorial designs. The... goal of such simulations is to investigate the connections between the D-optimality of a design and its geometric structure.

Greenhouse gas emission is an important issue and the largest source of it is from human activiti...es and from building sectors.

We generate all the Orthogonal Arrays (OAs) of a given size n and strength t as the union of a co...llection of OAs which belong to an inclusion-minimal set of OAs. We derive a formula for computing the (Generalized) Word Length Pattern of a union of OAs that makes use of their polynomial counting functions.

Algebraic sampling methods are a powerful tool to perform hypothesis tests on conditional spaces.... We analyse the link of the sampling method introduced in[6] with permutation tests and we exploit this link to build a two-step sampling procedure to perform two-sample comparisons for non-negative discrete exponential families.

This paper looks at permutation methods used to deal with hypothesis testing within the survival ...analysis framework. In the literature, several attempts have been made to deal with the comparison of survival curves and, depending on the survival and hazard functions of two groups, they can be more or less efficient in detecting differences.
