Stability Analysis and Local Influence Diagnostics for an Extreme-Value Regression Model of Anomalous Wind Gusts
José I. C. Lima, Raydonal Ospina, Michelli Barros +1
Extreme events in complex physical systems, such as anomalous wind gusts, often cause significant material and human damage. Their modeling is crucial for risk assessment and under…
Prediction Measures in Nonlinear Beta Regression Models
Patrícia Leone Espinheira, Luana C. Meireles da Silva, Alisson de Oliveira Silva +1
Nonlinear models are frequently applied to determine the optimal supply natural gas to a given residential unit based on economical and technical factors, or used to fit biochemica…
A general class of zero-or-one inflated beta regression models
Raydonal Ospina, Silvia L. P. Ferrari
This paper proposes a general class of regression models for continuous proportions when the data contain zeros or ones. The proposed class of models assumes that the response vari…
Inflated Beta Distributions
Raydonal Ospina, Silvia L. P. Ferrari
This paper considers the issue of modeling fractional data observed in the interval [0,1), (0,1] or [0,1]. Mixed continuous-discrete distributions are proposed. The beta distributi…
