rainfall is considered a highly valuable climatologic resource, particularly in arid regions. as one of the primaryinputs that drive watershed dynamics, rainfall has been shown to be crucial for accurate distributed hydrologicmodeling. precipitation is known only at certain locations; interpolation procedures are needed to predict this variablein other regions. in this study, the ordinary cokri...

The mixture property of the general multivariate Pareto MP distributions has been studied by Yeh (2004a). Arnold (1996) mentioned that any mixing distribution with support (0,∞) is a candidate for a frailty model. This fact drives Yeh to study the frailty structure of the MP distributions. It is discerned that the MP distributions is in the one-parameter kvariate Clayton family with k-variate A...

A 1 ( ) p -variate integral representation is given for the cumulative distribution function of the general p variate non-central gamma distribution with a non-centrality matrix of any admissible rank. The real part of products of well known analytical functions is integrated over arguments from ( , ).    To facilitate the computation, these formulas are given more detailed for 3. p  Furthe...

In this paper we apply the idea of Dixon resultant to algebraic differential equations and introduce the Dixon differential resultant. We prove that a necessary condition for the existence of a common solution of two algebraic differential equations is that the differential resultant is equal to zero, which actually provides a method of elimination and reduces a system of multi-variate differen...

A copula is a means of generating an n-variate distribution function from an arbitrary set of n univariate distributions. For the class of portfolio allocators that are risk averse, we use the copula approach to identify a large set of n-variate asset return distributions such that the relative magnitudes of portfolio shares can be ordered according to the reversed hazard rate ordering of the n...

Asian options are of particular importance for commodity products which have low trading volumes (e.g. crude oil), since price manipulation is inhibited. Hence, the pricing of such options becomes one of the most interesting fields. Since there are no known closed form analytical solutions to arithmetic average Asian options, many numerical methods are applied. This paper deals with pricing of ...

We describe experiments with a Naive Bayes text classifier in the context of anti-spam E-mail filtering, using two different statistical event models: a multi-variate Bernoulli model and a multinomial model. We introduce a family of feature ranking functions for feature selection in the multinomial event model that take account of the word frequency information. We present evaluation results on...

The use of Batemanmethod for solving the two-variable version of the twobody Lippmann–Schwinger equation without recourse to partial-wave decomposition is investigated. Bateman method is based on a special kind of interpolation of the momentum representation of the potential on a multi-variate grid. A suitable scheme for the generation of a multi-variate Cartesian grid is described. The method ...
