本文提出了一种新的先验和相应的算法,用于多项概率模型的贝叶斯分析。我们的新方法直接在已识别的参数空间上放置先验。关键是在协方差矩阵上指定一个先验,这样(1,1)元素就被固定在1,并且可以使用标准分布从后验中得出。分析结果得出,可用于帮助评估的前。芝加哥大学商学院,伊利诺伊州芝加哥东58街1101号,邮编60637。电子邮件:peter. rossi@gsb.uchicago.edu。
We present a new prior and corresponding algorithm for Bayesian analysis of the multinomial probit model. Our new approach places a prior directly on the identied parameter space. The key is the specication of a prior on the covariance matrix so that the (1,1) element if xed at 1 and it is possible to draw from the posterior using standard distributions. Analytical results are derived which can be used to aid in assessment of the prior.
