Nonlinear Simplex Regression Models
Patrícia Espinheira, Alisson de Oliveira Silva
In this paper, we propose a simplex regression model in which both the mean and the dispersion parameters are related to covariates by nonlinear predictors. We provide closed-form…
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…
FOCA: A Methodology for Ontology Evaluation
Judson Bandeira, Ig Ibert Bittencourt, Patricia Espinheira +1
Modeling an ontology is a hard and time-consuming task. Although methodologies are useful for ontologists to create good ontologies, they do not help with the task of evaluating th…
Prediction Measures in Beta Regression Models
Patrícia L. Espinheira, Luana Cecília Meireles da Silva, Alisson de Oliveira Silva
We consider the issue of constructing PRESS statistics and coefficients of prediction for a class of beta regression models. We aim at displaying measures of predictive power of th…
