Seminar on econometrics at Waseda University

On April 19 our poject leader Prof. Hidehiko Ichimura held a seminar entitled "The Influence Function of Semiparametric Estimators" at the Waseda University Institute of Political Economy.

Prof. Ichimura's talk was based on his work with Prof. Whitney Newey from the Economics Departement of the Massachusetts Institute of Technology.

Their research explores the usages of the influence function of semiparametric estimators, the ways in which it can be calculated and examines the conditions for the validity of the influence function calculation, such as Frechet differentiability, nonparametric convergence rates, stochastic equicontinuity, and small bias conditions.
