贝叶斯概率回归中一种新的蒙特卡罗抽样方法

A new Monte Carlo sampling in Bayesian probit regression

Yuzo Maruyama, William E. Strawderman

摘要:

本文从贝叶斯的角度研究了概率单位回归问题,并给出了当回归参数的先验分布为均匀分布时的后验分布的另一种形式。这种新的形式允许简单的蒙特卡罗模拟的后,而不是MCMC模拟研究的文献中,因此可能是更有效的计算。我们还提供了第一时刻和第二时刻的替代显式表达式。此外,我们提供类似的结果高斯先验。

英文摘要:

We study probit regression from a Bayesian perspective and give an alternative form for the posterior distribution when the prior distribution for the regression parameters is the uniform distribution. This new form allows simple Monte Carlo simulation of the posterior as opposed to MCMC simulation studied in much of the literature and may therefore be more efficient computationally. We also provide alternative explicit expression for the first and second moments. Additionally we provide analogous results for Gaussian priors.
