Abstract

A deformed exponential family is a natural generalization of an ordinary exponential family, and it is useful for robust statistics. However, the standard maximum likelihood method does not work efficiently for deformed exponential families.

In this talk, we introduce generalized estimating functions for deformed exponential families, and give information geometric interpretations for such estimating functions. In particular, we construct dually flat structures and divergence functions on deformed exponential families from the viewpoint of unbiasedness of estimating functions.
