內容簡介
現在商業競爭日益激烈，有效做出商務決策變得至關重要。《商務統計:決策與分析(英文版)》從實際的商業問題出發，告訴讀者如何尋找模式從數據建立統計模型，以及如何提供調查結果。書中涵蓋了套用統計學在當代商務經濟領域中幾乎所有的重要套用，並且統計軟體（包括Excel、Mirlitab等）的使用貫穿全書。
作者簡介
斯泰恩，Robert A.Stine，於普林斯頓大學獲得博士學位。自1983年以來他一直在賓夕法尼亞大學沃頓商學院講授商務統計學課程。在任教期間，他獲得了多項教學獎，包括MBA核心教學獎、David W.Hauck優秀教學獎。他的研究領域包括計算機軟體、時間序列分析和預測、與模型識別和選擇相關的一般問題等。
福斯特，Dean P.Foster，於馬里蘭大學獲得博士學位。他曾在芝加哥大學任教，自1992年以來任教於賓夕法尼亞大學沃頓商學院。他講授的課程有商務統計初步、機率論與馬爾可夫鏈、統計計算和高等統計學等。其研究領域包括隨機過程的統計推斷、博弈論、機器學習和變數選擇。
