1. Generalized entropy indices to measure α- and β-diversities of macrophytes
A family of entropy indices constructed in the framework of Tsallis entropy formalism is used to investigate ecological diversity. It represents a new perspective in ecology because a simple equation can incorporate all aspects of α-diversity, from richness to dominance and can be also related to a measure of species rarity. In addition, a generalized Kullb

2. A numerical study of the Kullback-Leibler distance in functional magnetic resonance imaging
The Kullback-Leibler distance (or relative entropy) is applied in the analysis of functional magnetic resonance (fMRI) data series. Our study is designed for event-related (ER) experiments, where a brief stimulus is presented and a long period of rest is followed. In particular, this relative entropy is used as a measure of the "distance" between the probabi

3. Statistical Inference in Methods of Analysis of Functional Magnetic Resonance / Inferência estatística em métodos de análise de ressonância magnética funcional
No presente trabalho, conceitos de inferência estatística são utilizados para aplicação e comparação de diferentes métodos de análise de sinais de ressonância magnética funcional. A idéia central baseia-se na obtenção da distribuição de probabilidade da variável aleatória de interesse, para cada método estudado e sob diferentes valores da

4. Intervalo de confiança para avaliação de bioequivalencia individual utilizando a medida de Kullback-Leibler
Bioequivalence trials are conducted to show that two formlllations, a reference dmg R and a test T, produces similar bioavailabitity. In Brazil, the introduction of the generic drug started in 1999 and the current analysis of the pharmacokinetics measures for rate and extent of the absorption is the average bioequivalence (ABE) which is not sufficient to gua

5. Fine-Scale Mapping of Quantitative Trait Loci Using Historical Recombinations
With increasing popularity of QTL mapping in economically important animals and experimental species, the need for statistical methodology for fine-scale QTL mapping becomes increasingly urgent. The ability to disentangle several linked QTL depends on the number of recombination events. An obvious approach to increase the recombination events is to increase
