2. Estimating Poisson pseudo-maximum-likelihood rather than log-linear model of a log-transformed dependent variable
Abstract Purpose The purpose of this study is to account for a recent non-mainstream econometric approach using microdata and how it can inform research in business administration. More specifically, the paper draws from the applied microeconometric literature stances in favor of fitting Poisson regression with robust standard errors rather than the OLS lin

3. QUADRATURE ALGORITHMS FOR PHASE EQUILIBRIUM OF CONTINUOUS MIXTURES
Abstract Several methods for computing the Gauss-Christoffel quadrature used for the adaptive characterization of continuous mixtures were compared as to their efficiency and robustness. Two mixtures with molar fraction distribution given by truncated gamma distributions were used. We analyzed the Product-Difference, the Golub-Welsch, the Long Quotient-Modif

4. Modelos estatísticos para geração da Planta de Valores Genéricos: uma aplicação em município de pequeno porte
Resumo Importante fonte de arrecadação dos municípios, o IPTU tem como base de cálculo o valor venal do imóvel, estabelecido pela Planta de Valores Genéricos (PVG), a qual está desatualizada na maior parte dos municípios brasileiros. Assim, o objetivo deste trabalho foi utilizar a econometria espacial para gerar um modelo que permita determinar o val

5. Practical rules for summing the series of the Tweedie probability density function with high-precision arithmetic
Abstract: For some ranges of its parameters and arguments, the series for Tweedie probability density functions are sometimes exceedingly difficult to sum numerically. Existing numerical implementations utilizing inversion techniques and properties of stable distributions can cope with these problems, but no single one is successful in all cases. In this wor

12. SENSITIVITY ANALYSIS FOR MODEL COMPARISON AND SELECTION IN TISSUE ENGINEERING
ABSTRACT Computational modeling has been proven to be very useful in tissue engineering over the past years. Because the model is a simplification of the experimental system, the processes accounted for in the model should be analyzed carefully. However, new and complex models are usually proposed without a clear comparison with the basic ones. In this study
