在台灣現在中信銀行經營的樂透彩票系統上，我們針對「6/49大樂透」這部份做討論，試圖去探討每顆球的出現的是否符合理論上計算出來的機率，如果沒有，那又是以怎樣的形式在出現。 依照「6/49大樂透」固定時間每期開獎的形式，我嘗試以逐次概似比例檢定(Sequential Likelihood Ratio Test) 來做分析，分成1.以最近一期為初始值去計算接下來的Lemda值；2.以近49期為初始值去計算接下來的Lemda值；3.以持有所有期數為初始值去計算接下來的Lemda值三個部份。觀察並討論每個部份得到的結果，進而嘗試去做模擬來驗證結果。 In the lottery system of Taiwan CITIC BANK, our discussion focus on 「6/49 BIG LOT」.We try to test if the probabilities of ball`s appearance are agree with the theoretical counting probability ? If not , what is the form of ball`s appearance ? According to the form that lottery run in fix time of 「6/49 BIG LOT」, we try to make analysis by using 「Sequential Likelihood Ratio Test」. We make analysis in three parts： 1.Using the nearest run to calculate the first lemda value . 2.Using the nearest 49 runs to calculate the first lemda value . 3.Using all the runs I collect to calculate the first lemda value . Scanning the result of every part and make of discussion of it . Finally , making simulation to verify the result .
