Bootstrap prediction intervals in beta regressions

A class of improved heteroskedasticity-consistent covariance matrix estimators

The heteroskedasticity-consistent covariance matrix estimator proposed by White (1980), also known as HC0, is commonly used in practical applications and is implemented into a number of statistical software. Cribari–Neto, Ferrari & Cordeiro (2000) have developed a bias-adjustment scheme that delivers bias-corrected White estimators. There are several variants of the original White estimator that also commonly u...

Diagnostic tools in beta regression with varying dispersion

Improved likelihood inference in Birnbaum-Saunders regressions

HETEROGENEIDADE DO TRABALHO E TAXA DE LUCRO EM MARX

The purpose of this paper is to analyze the dynamic behavior of the rate of profit in a marxian framework, once human capital is incorporated as a production factor. In this context, a set of sufficient conditions for an increasing behavior of the rate of profit and the wage rate along the accumulation process is derived.; O objetivo do presente artigo é o de analisar o comportamento dinâmico da taxa de lucro e...
