Análise de resíduos em modelos de regressão von Mises.

Abstract

Datainvolvingangulararepresentinthemostdiverseareasofscience. Toanalyze them is necessary to introduce an appropriate theory and to study specific and appropriate statistics as well, different from that we use for linear data. When the interest is to formulate, to adjust and to make diagnostics on regression models, the nature of the variables must be considered. In this work, we use the von Mises regression models to investigate the circular-linear association and discuss two standardized residuals defined from the component of the deviance function whose probability distributions can be approximated by the normal standard distribution defined for linear data.
