The distribution form of safety factor is standard normal distribution while soil parameter distribution is normal or lognormal distribution.
土性参数的分布形式取正态分布或者对数正态分布时，安全系数的分布均呈标准正态分布；
The models were estimated via Gibbs sampler with data augmentation by a mixture of standard exponential distribution and standard normal distribution to represent the asymmetric Laplace distribution.
由于模型参数的后验条件分布没有确定的分布形式，通过数据扩充得到参数的完全条件分布从而实现模型参数的贝叶斯估计。
