Robust three-step regression based on comedian and its performance in cellwise and casewise outliers
(Maestría en Matemáticas AplicadasEscuela de Ciencias. Departamento de Ciencias Básicas, 2018)
Cellwise and casewise outliers may appear both at the same time in real data. Few methods have developed statistical methods to deal both types of outliers in regression models. We propose a new three-step regression method ...
On ecological aspects of dynamics for zero slope regression for water pollution in Chile
(2019)
Zero slope regression is an important problem in chemometrics, ranging from challenges of intercept-bias and slope 'corrections' in spectrometry, up to analysis of administrative data on chemical pollution in water in the ...
A fast electric load forecasting using neural networks
(2000-12-01)
The objective of this work is the development of a methodology for electric load forecasting based on a neural network. Here, it is used Backpropagation algorithm with an adaptive process based on fuzzy logic. This methodology ...

A bayesian approach to parameter estimation in simplex regression model: a comparison with beta regression
(Universidad Nacional de Colombia, 2013)
Some variables are restricted to the open interval (0; 1) and several methodshave been developed to work with them under the scheme of the regressionanalysis. Most of research consider maximum likelihood methods andthe use ...
Proposal of a new model for CL regression or maintenance during pregnancy on the basis of timing of regression of contralateral, accessory CL in pregnant cows
(TheriogenologyEstados Unidos, 2017-02)
In bovine pregnancy, regression or maintenance of the corpus luteum (CL) is mediated through local communication pathways between embryo, uterus, and ovary with Days 16 to 25 of pregnancy generally recognized as the pivotal ...

Critical points in logistic growth curves and treatment comparisons
(Universidade de São Paulo (USP), 2012-01-01)
Several biological phenomena have a behavior over time mathematically characterized by a strong increasing function in the early stages of development, then by a less pronounced growth, sometimes showing stability. The ...
