误设定下后验分布的收敛速度

On rates of convergence for posterior distributions under misspecification

Heng Lian

摘要:

我们将Walker(2003,2004)的方法推广到错误指定模型的情况。基于一个涉及鞅的关键恒等式,给出了判定收敛速度的一个充分条件。我们还粗略地表明,通过使用测试得到的结果也可以得到我们的方法,这表明了潜在的更广泛的适用性,这种方法。

英文摘要:

We extend the approach of Walker (2003, 2004) to the case of misspecified models. A sufficient condition for establishing rates of convergence is given based on a key identity involving martingales, which does not require construction of tests. We also show roughly that the result obtained by using tests can also be obtained by our approach, which demonstrates the potential wider applicability of this method.
