So data warehouse technique is introduced in fault diagnosis. takes gear case as the instance, the paper uses the data mining to generate rules distinguishing the faults of gear case, and then uses these rules to diagnose unknown fault
對此，在故障診斷領域引入數據倉庫技術，並以齒輪箱為例，通過數據挖掘產生區分齒輪箱各種故障的規則，並利用這些規則來診斷未知故障。 -
( 3 ) how to design the bayesian test method about the parameter ' s linear hypothesis according to the relationship between the multivariate t distribution and f distribution. ( 4 ) the bayesian diagnosis and unit root test method about the random error series. ( 5 ) the bayesian mean value quality control chart when the variance is known and the mean value - standard error control chart when the variance is unknown
然後，研究了擴散先驗分佈下單方程模型參數的貝葉斯估計理論，證明了模型系數的后驗分佈為多元t分佈，模型誤差項方差的后驗估計為逆gamma分佈；根據多元t分佈和f分佈之間的關系，構造了模型系數線性假設檢驗的貝葉斯方法；根據hpd置信區間構造了隨機誤差序列自相關的貝葉斯診斷和單位根檢驗方法，並利用單方程模型的貝葉斯推斷理論研究了方差已知時的貝葉斯均值控制圖和方差未知時的貝葉斯均值?標準差控制圖。 -
