In this article, a multivariate extension of the unit-sinh-normal (USHN) distribution is presented. The new distribution, which obtained from conditionally specified distributions methodology, absolutely continuous, and its marginal are univariate USHN. properties USHN studied in detail, statistical inference carried out classical approach using maximum likelihood method. suitable for modeling ...

This paper concerns segmented multivariate regression models, models which have different linear forms in different subdomains of the domain of an independent variable. Without knowing that number and their boundaries, we first estimate the number of these subdomains using a modified Schwarz criterion. The estimated number of regions proves to be weakly consistent under fairly general condition...

Bayesian analyses of multivariate binary or categorical outcomes typically rely on probit or mixed effects logistic regression models that do not have a marginal logistic structure for the individual outcomes. In addition, difficulties arise when simple noninformative priors are chosen for the covariance parameters. Motivated by these problems, we propose a new type of multivariate logistic dis...

Gully erosion when it comes to positive processes in the most severe operating conditions and the most favorable conditions for the performance of other words is a positive process. One of the most important issues discussed gully erosion monitoring and evaluation of benchmarking is to extract and identify the type of erosion. In this paper the groove factor and drainage ditches, and selected a...
