We use discriminant analysis to describe and predict market classifications. Potential discriminators are derived from relevant characteristics of market indices, in particular from the ret...

Portfolio selection requires an estimate of the degree of association between assets. The Pearson correlation coefficient ρ is the most common measure and estimates the linear correlation implied by the underlying bivariate distribution. Correlation

It has been empirically verified that the strength of dependence in stock markets usually rises with volatility. In this paper we exploit this stylized fact combined with local maximum likelihood estimation of copula models to analyze the dynamic joi

The equations of magnetohydrodynamics (MHD) are written for non-uniform viscosity and resistivity – the latter in the cases of Ohmic and anisotropic resistivity. In the case of Ohmic (anisotropic) diffusivity, there is (are) one (two) transverse co

The present paper concerns Alfven waves, in a resistive and viscous atmosphere, under a steep temperature gradient (Section 1). The dissipative Alfven wave equation is deduced assuming uniform vertical background magnetic field, and allowing for arbi

Allergic disorders, such as seasonal rhinitis and asthma, are increasing causes of morbidity worldwide and often result from exposure to airborne pollen. Pollen allergy has a remarkable clinical impact all over Europe. In fact, epidemiological longit

We use the Box-Jenkins approach to fit an autoregressive integrated moving average (ARIMA) model to dengue incidence in Rio de Janeiro, Brazil, from 1997 to 2004. We find that the number of dengue cases in a month can be estimated by the number of de

We derive the maximum bias functions of the MM-estimates and the constrained M-estimates or CM-estimates of regression and compare them to the maximum bias functions of the S-estimates and the $\tau$-estimates of regression. In these comparisons, the

We consider dissipative Alfven waves in a viscous atmosphere with a magnetic field, so that the electrical conductivity is considered as a non-diagonal tensor. Under a vertical uniform magnetic field we consider transverse magnetic and velocity pertu
