Shmueli et al. (2005) introduced the COM–Poisson–binomial distribution, but they did not study the mathematical properties of this family of distributions. In this paper, we discuss some properties and an asymptotic approximation of it by the COM–Poisson distribution. Moreover, three...

Natural gas combustion experiments were conducted in a lean burn CNG engine to uncover the regularities of cyclic combustion variations (CCVs) in different operating conditions. The effects of the engine operation parameters on the correlations between pressure related characteristic parameters...

The coherence of a random matrix, which is defined to be the largest magnitude of the Pearson correlation coefficients between the columns of the random matrix, is an important quantity for a wide range of applications including high-dimensional statistics and signal processing. Inspired by...

In the frame of this article we submitted the practical possibilities to analyse the stock market activity in Romania, by means of the linear regression model. Thus, the study is focusing on the existing correlations between the yield of a portfolio formed by ten financial assets issued by...

Understanding the uncertainty of climate models in space and time is necessary to help water resources managers and hydrologists in the selection of appropriate model for a specific application. In this paper, we use three separate methods to evaluate and compare the utility of 14 climate models...

This paper explored the potential of Backpropagation Neural Network (BNN) and M5 model tree based regression approach to estimate the mean annual flood. Data used in this study were taken from an earlier study by Swamee et al. (J Water Resour Plan Manage 121:403–407, <CitationRef CitationID="CR23">1995</CitationRef>) for 93 Indian...</citationref>

A new means of estimating the correlation coefficient for cluster binary data in the regression settings is introduced. The creation of this method is founded upon the violation of Bartlett’s second identity when adopting the binomial distributions to model binary data that are correlated. The...

In this paper, a multivariate form of truncated generalized Cauchy distribution (TGCD), which is denoted by (MVTGCD), is introduced. The joint density function, conditional density function, moment generating function and mixed moments of order <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$${b=\sum_{i=1}^{k}b_{i}}$$</EquationSource> </InlineEquation> are obtained. Making...</equationsource></inlineequation>

Denecke and Müller (CSDA 55:2724–2738, <CitationRef CitationID="CR2">2011</CitationRef>) presented an estimator for the correlation coefficient based on likelihood depth for Gaussian copula and Denecke and Müller (J Stat Planning Inference 142: 2501–2517, <CitationRef CitationID="CR3">2012</CitationRef>) proved a theorem about the consistency of general estimators based on...</citationref></citationref>

На конкретном примере выявлена необходимость неформальной подготовки данных для получения репрезентативных результатов при проведении статистического...
