Pelagic microplastics around an archipelago of the Equatorial Atlantic.

TL;DR: It is shown that synthetic polymers are present in subsurface plankton samples around Saint Peter and Saint Paul Archipelago in the Equatorial Atlantic Ocean and a generalised linear model (GLM) is proposed that suggests the existence of an outward gradient of mean plastic-particle densities.
Journal ArticleDOI

Birnbaum–Saunders statistical modelling: a new approach:

TL;DR: A new approach for Birnbaum–Saunders regression models is introduced, which allows to analyze data in their original scale and to model non-constant variance and four types of residuals for these models are proposed.
Journal ArticleDOI

A robust method for linear regression of symbolic interval data

TL;DR: This paper introduces a new linear regression method based on the symmetrical linear regression methodology such that the prediction of the lower and upper bounds of the interval value of the dependent variable is not damaged by the presence of interval-valued data outliers.
Journal ArticleDOI

A Multivariate Log-Linear Model for Birnbaum-Saunders Distributions

TL;DR: New multivariate generalized Birnbaum-Saunders regression models are proposed and derived using the maximum likelihood method and the EM algorithm to estimate their parameters and are illustrated with real-world multivariate fatigue data.
Journal ArticleDOI

Robust multivariate control charts based on Birnbaum–Saunders distributions

TL;DR: In this article, a robust methodology using multivariate quality control charts for subgroups based on generalized Birnbaum-Saunders distributions and an adapted Hotelling statistic is proposed for Phases I and II of control charts.
