Title: The Semiparametric Exchangeable Model
Author(s): Stephine Keeton*+
Companies: Food and Drug Administration
Address: 7500 Standish Place, Rockville, MD, 20855,
Keywords: exchangeability ; semi parametric
Abstract:

We generalize the class of exchangeable parametric distributions and present a unified model. We also propose a semi parametric regression model and develop procedures of efficient estimation. Because independence is relaxed to exchangeability, the unified model for exchangeability improves models for which independence is assumed. Semi parametric models, as a modern regression, share the advantages of both parametric and nonparametric models. The proposed semi parametric exchangeable model is anticipated to ameliorate statistical modeling, in particular, in teratology.
