In this paper, we propose a simplex regression model in which both the mean and the dispersion parameters are related to covariates by nonlinear pred…

The discrete cosine transform (DCT) is the key step in many image and video coding standards. The 8-point DCT is an important special case, possessin…

Polarimetric synthetic aperture radar (PolSAR) has achieved a prominent position as a remote imaging method. However, PolSAR images are contaminated …

The principal component analysis (PCA) is widely used for data decorrelation and dimensionality reduction. However, the use of PCA may be impractical…

A relationship between the Riemann zeta function and a density on integer sets is explored. Several properties of the examined density are derived.

In this paper, we introduce the Birnbaum-Saunders power series class of distributions which is obtained by compounding Birnbaum-Saunders and power se…

Matching a wavelet to class of signals can be of interest in feature detection and classification based on wavelet representation. The aim of this wo…

The modeling and analysis of lifetimes is an important aspect of statistical work in a wide variety of scientific and technological fields. For the f…

Several measures for the density of sets of integers have been proposed, such as the asymptotic density, the Schnirelmann density, and the Dirichlet …

Given an arbitrary continuous probability density function, it is introduced a conjugated probability density, which is defined through the Shannon i…

Koblitz curves are a special set of elliptic curves and have improved performance in computing scalar multiplication in elliptic curve cryptography d…

We consider the issue of constructing PRESS statistics and coefficients of prediction for a class of beta regression models. We aim at displaying mea…

We consider the issue of performing accurate small-sample testing inference in beta regression models, which are useful for modeling continuous varia…

Nonlinear models are frequently applied to determine the optimal supply natural gas to a given residential unit based on economical and technical fac…

This paper introduces a fast algorithm for simultaneous inversion and determinant computation of small sized matrices in the context of fully Polarim…

The discrete Tchebichef polynomials are a set of discrete variable orthogonal polynomials [HTF53]. The kth order discrete Tchebichef polynomials are given by the following closed form expression [Swamy2008DTT]:

The usage of linear transformations has great relevance for data decorrelation applications, like image and video compression. In that sense, the dis…

The scaled complex Wishart distribution is a widely used model for multilook full polarimetric SAR data whose adequacy has been attested in the liter…

Standard game theory assumes that the structure of the game is common knowledge among players. We relax this assumption by considering extensive game…

This paper introduces a new fast algorithm for the 8-point discrete cosine transform (DCT) based on the summation-by-parts formula. The proposed meth…

In this paper, we introduce a new class of distributions which is obtained by compounding the extended Weibull and power series distributions. The co…
