摘要: | 本研究係採SAS程式資料模擬的方式,對於三種常見及存在於現實 生活的分配進行研究,包括:常態分配、均等分配及伽瑪分配。探討母體 為這三種分配特性組合時,若採行樣本加權推估與樣本直接推估的平均數 與母體平均數的差異程度。提供管理層面及統計分析層面瞭解,當使用不 適當的統計分析方法時,用以推估母體平均值,將是相當危險的。因此, 必須確時掌握樣本調查前後的各種情況,作為選擇統計分析方法的參考依 據。 This Review of thesis is to disscuss the differences between population mean weighted and unweighted estimates with simulation method , which the population is constituent of Normal distribution , Uniform distribution and Gamma distribution. Provide management and statistical analysis degree members to understand ,it will be very dangerous when they misuse statisticalanalysis methods. In order to choice the proper statistical analysis methods , so we must know well the sample's situation of theSurvey from beginningto end. |
