About 統計計算機

Statistics based computer-aided engineering or statistical basis for the science and design

Puli College 為工程師及工程科系學生發展一套計算機,分別為基礎計算機、科學計算機、統計計算機,以及解方程計算機。

本機為統計型計算機,為輔助工程或科學之基礎統計而發展。統計型計算機具三項功能;

(1) 輸入n筆資料,計算統計量(平均值、標準差及偏度係數)

其中,n筆資料分別為x1,x2,x3,…,xn;

平均值xm定義為xm=(x1+x2+x3+…+xn)/n;

標準差σ定義為σ={[(x1-xm)2+(x2-xm)2+(x3-xm)2+…+(xn-xm)2]/(n-1)}0.5;

偏度係數sk定義為

sk={[(x1-xm)3+(x2-xm)3+(x3-xm)3+…+(xn-xm)3]╳n/(n-1)/(n-2)}/ σ3;

(2) 輸入標準單位Z,計算累加機率值CDF(Z)

此功能基於常態機率分佈假設,其中,標準單位Z定義為Z=(x-xm)/σ;CDF(Z)為常態分佈下,標準單位Z值所對應之累加機率。

(3) 輸入累加機率值CDF(Z),計算標準單位Z

此功能亦基於常態機率分佈假設,標準單位Z及累加機率CDF(Z)之定義同上。
