隱馬可夫模型在發育過程上之應用

Abstract

本論文是探討非裔美國青少年發育過程之變化，由於Tanner階段普遍被用來評估發育過程的階段，但是，人類成長發育是連續性的且Tanner階段是帶有本身變異的次序出象，則誤判至鄰近階段是很有可能發生的，所以，在本論文中，我們特別考量用隱馬可夫模型來分析，以便討論非裔青少年在發育階段所需持續之時間及評估每階段的轉移機率。

This thesis discusses the changes in adolescent African American boys and girls. Tanner stage is commonly used for assessment of the status of sexual development. Since human growth is continuous and Tanner stage has an ordinal outc- ome with self-rating, it is possible to rate to adjacent stages. Thus, this thesis specially considers Hidden Markov Model to analyze. It is used for determining durations of Tanner stages among adolescent African American children and rating the transition probability.
