Mathematical Model of Non-stationary Heat Conduction in the Wall: Asymmetric Problem with the Boundary Conditions of Imperfect Heat Transfer

MATEC Web of Conferences, 2016
This paper deals with the study of a non-stationary heat conduction in the solid wall. It is focused on mathematical modelling of its asymmetric heating and cooling by imperfect heat transfer to both sides of the wall.

Bayesian quantile semiparametric mixed-effects double regression models

Statistical Theory and Related Fields, 2021
Semiparametric mixed-effects double regression models have been used for analysis of longitudinal data in a variety of applications, as they allow researchers to jointly model the mean and variance of the mixed-effects as a function of predictors ...

On Asymmetric Discrete Laplace Distributions and Processes

Sankhya A
Abstract After reviewing two asymmetric discrete Laplace models, some asymmetric discrete Laplace processes are introduced and investigated. The problem of developing bivariate discrete Laplace processes is also addressed.

Portfolio selection based on asymmetric Laplace distribution, coherent risk measure, and expectation-maximization estimation

, 2018
In this paper, portfolio selection problem is studied under Asymmetric Laplace Distribution(ALD) framework. Asymmetric Laplace distribution is able to capture tail-heaviness, skewness, andleptokurtosis observed in empirical financial data that cannot be ...
