马尔可夫链从任意初始值x0开始，并且算法运行多次迭代，直到“初始状态”被“忘记”为止。这些被丢弃的样本称为预烧（burn-in）。其余的x可接受值集代表分布P（x）中的样本Metropolis采样一个简单的Metropolis-Hastings采样让我们看看从 伽玛分布 模拟任意形状和比例参数，使用具有Metropolis-Hastings采样算法。

I will fit the model, aeesee convergence, and discard any burn-in samples before making any posterior inference. For this I will run 2 separate chains and use Gelman_Rubin convergence disgnostic. Recall that when fitting a model previously I defined the jags model, coverted the data to a ...
