Estimators, escort probabilities, and phi-exponential families in statistical physics
英文摘要：
The lower bound of Cramer and Rao is generalized to pairs of families of probability distributions, one of which is escort to the other. This bound is optimal for certain families, called phi-exponential in the paper. Their dual structure is explored.
