| dc.description.abstract (摘要) | 在許多科學領域裡所蒐集到的資料是具有方向性且落在單位球上，而在具有方向性且在單位球上的資料分配中，最重要也是最常使用的分配是3維的von Mises-Fisher分配。在過去有許多學者專家曾分析過具有3維von Mises-Fisher分配的資料，其中Nunez-Antonio和Gutierrez-Pena (2005)也曾利用全貝氏法來分析此種資料。本文首次嘗試利用半母數貝氏法來分析具有3維von Mises-Fisher分配的資料。除了介紹如何估計參數以及預測未來資料的機率密度函數外，本文也將檢定兩組分別服從不同3維von Mises-Fisher分配的資料其平均方向是否相同，並且提供選取先驗分配與其參數之建議。 | zh_TW |
