演題      Likelihood Tilting

概要
The concept of a tilted distribution has proved to be of great value in
statistical inference.  In this talk, I shall discuss some examples of
tilting, and shall examine how likelihood tilting, in particular, can
provide a different paradigm for likelihood methodology.  The integrated
tilt of a distribution will be developed as an operator, and model
assumptions shall be interpreted as families of operators acting on
distributions.

Examples from parametric and semiparametric inference will be studied.
