| TOPIC | Frequentist’s Properties of Posterior Distributions in Semiparametric Regression Models | ||
| 소개 및 안내사항Content | In a smooth semiparametric model, the marginal posterior distribution for the fi-nite dimensional parameter of interest is expected to be asymptotically equivalent to the sampling distribution of any efficient estimator. The assertion leads to asymptotic equiv-alence of credible and confidence sets for the parameter of interest and is known as the semiparametric Bernstein-von Mises (sBvM) theorem. In this talk, the sBvM theorem is considered in regression models in which errors with symmetric densities play a role. Then, it is extended to a high-dimensional semiparametric model where most compo-nents of the regression coefficient are zero. Various asymptotic properties such as optimal convergence rate, adaptation, distributional approximation and selection consistency are studied. The results guarantee asymptotic efficiency, adaptiveness to unknown sparsity level and error density, model selection consistency and valid uncertainty quantification for Bayes procedures. |
