    Summary: 一般而言,我們使用完全條件分佈,來執行吉氏取樣,藉以獲取相關聯合分佈的樣本點。然而吉氏取樣的缺點在於收斂很慢,於是有文獻提出使用不完全條件分佈,進行吉氏取樣,其結果確實可有效地加快收斂速度。然而使用不完全條件分佈時必須注意取樣的順序,因為不同的取樣順序所對應的馬可夫鏈之平穩分佈不盡相同,因此必須知道哪一個平穩分佈是目標分佈。在本研究中,我們將探討如何決定對的取樣順序,這也使得未來研究中在使用吉氏取樣時,在條件分佈的挑選上有更彈性的選擇。 In general, we implement the Gibbs sampler, by using full conditional distributions, to obtain the sample of the corresponding joint distribution. However, the shortcoming of the Gibbs sampler is its slow convergence. New strategy is provided because it can result in samplers with much better convergence properties. Nevertheless, it must be performed in a certain order to maintain the target stationary distribution. In this studying, we will discuss that how to choose the correct orders such that the Gibbs sampler can be implemented via non-full conditional distributions.
