根据样本 X 的分布Pθ及θ的先验分布π(θ),用概率论中求条件概率分布的方法,可算出在已知X=x的条件下,θ的条件分布 π(θ|x)。因为这个分布是在抽样以后才得到的,故称为后验分布。

计算出参数的后验分布后,可进行沉降预测分布的计算。
After calculating the parameters' posterior distribution, the predictive distribution of settlement can also be obtained.
在大多数情况下,基于后验分布的贝叶斯解会优于传统解。
In most cases, Bayes solution based on the mean of the posterior distribution will be better than the traditional one.
同时,各种统计计算方法的合理运用也可将后验分布的产生化繁为简。
Meanwhile, various skills of statistical calculation can also help to simplify the way of generating the posterior distribution if they are properly utilized.
