Abstract

The goal of statistics is to provide explanations (models) of observed data.We are given some data and have to infer a plausible probabilistic hypothesis explaining it. Consider, for example, the following scenario.We are given a "black box"We have turned the box on (only once) and it has produced a sequence x of million bits. Given x, we have to infer a hypothesis about the black box.
