Power Families of Bivariate Proportional Hazard Models

open access: yesMathematics, 2022
In this paper, we propose a general class of bivariate proportional hazard distributions, which is based on the family of asymmetric proportional hazard distributions and the bivariate Pareto copula.

TWO-STAGE DEA ESTIMATION OF TECHNICAL EFFICIENCY: COMPARISON OF DIFFERENT ESTIMATORS [PDF]

open access: yesReview of Agricultural and Applied Economics, 2022
Research background: The challenge of resource limitations requires that farmers make judicious use of resources to maximize output and profit levels. This can be achieved through assessment of resource-use efficiency of farmers by estimating the level ...

An Exponentiated Multivariate Extension for the Birnbaum-Saunders Log-Linear Model

open access: yesMathematics, 2022
In this work, a bivariate extension of the univariate exponentiated sinh-normal distribution is proposed. The properties of the new distribution, which is called the bivariate exponentiated sinh-normal distribution, are studied in detail, and the maximum

A sampling strategy for assessing habitat coverage at a broad spatial scale

open access: yesEcological Indicators, 2022
The quantitative assessment of habitat conservation status is a major task for European Union member states in compliance with Council Directive 92/43. One goal of the European 2030 Biodiversity Strategy is the effective management of habitats that show ...

Conditional Estimation in Two-Stage Adaptive Designs [PDF]

open access: yesBiometrics, 2017
Summary We consider conditional estimation in two-stage sample size adjustable designs and the consequent bias. More specifically, we consider a design which permits raising the sample size when interim results look rather promising, and which retains the originally planned sample size when results look very promising.

Off-Grid DoA Estimation via Two-Stage Cascaded Neural Network

open access: yesEnergies, 2021
This paper introduces an off-grid DoA estimation via two-stage cascaded network which can resolve a mismatch between true direction-of-arrival (DoA) and discrete angular grid.

Two-Stage Fast DOA Estimation Based on Directional Antennas in Conformal Uniform Circular Array

open access: yesSensors, 2021
In conformal array radar, due to the directivity of antennas, the responses of the echo signals between different antennas are distinct, and some antennas cannot even receive the target echo signal.
