| Research Abstract |
In this study, we focused on a class of statistical models associated with the Bregman divergence which achieves robust estimation in calculating statistics. We have proposed some methods for estimation of these models, and analyzed some properties from the viewpoint of application for data analysis. Particularly, we generalized the definition of statistical independence by using an extension of the multiplication rule between positive values; the extension is derived from the Bregman divergence. We have shown that the proposed statistical models based on generalized independence can be useful tools in practical data analysis by alleviating the conditional independence assumed in the conventional methods.
