Different countries used the growth Gompertz function at the beginning of the COVID-19 pandemic to model the number of cumulative infected cases since it provides reasonable results. Such a model allows only one mode, but the pandemic evolution has e

Considering the possible correlation between the characteristics (variables) in multivariate stratified random sampling, a modified Prekopa’s approach is suggested for the problem of optimum allocation in multivariate stratified random sampling. An

In this article, we introduce the matrix extension of the closed skew-normal distribution and give two constructions for it: a marginal one and another based on hidden truncation. Important basic properties of the distribution are presented such as i

We consider the optimization of a response surface given by a polynomial model. In this article the problem is stated as a stochastic optimization problem. For the first-order model, the E-Model technique is used to find the maximum and stationary po

Skewness is an intrinsic characteristic in Stochastic Frontier Analysis (SFA), where it is used as a measure of technical inefficiency. We discuss the use of skew normality in SFA. We consider stochastic frontier analysis in the common setting Normal
