DataFitting 是一個功能強大的統計分析程式，可執行線性和非線性回歸分析（即曲線擬合）。DataFitting 確定方程的參數值（您指定方程的形式）使方程最適合一組資料值。DataFitting 可以處理線性、多項式、指數函數和一般非線性函數。 DataFitting 執行真正的非線性回歸分析，它不會將函數轉換為線性形式。因此，它可以處理無法線性化的函數，例如： y = (a - c) = exp(- b = x) = c。 快速搜尋描述資料的最佳公式： DataFitting 使學生、教師、工程師、研究人員和其他專業人員能夠通過將大量方程放在指尖，為最複雜的數據找到理想的模型。它內置庫，包括從簡單線性方程到高階多項值的線性和非線性模型。 以圖形方式檢視曲線擬合結果： 數據擬合后，DataFitting 會根據標準誤差的統計標準自動排序和繪製擬合方程。您可以預覽圖形，並在多個不同配置中輸出出版物品質圖表。為所選擬合方程生成殘差圖和參數輸出。報告面板內還提供數據、統計數據和數位摘要。 資料擬合具有以下功能： * 38 位元精密數學模擬器，用於正確擬合高階多項式和理性。 * 非線性擬合的堅固擬合能力，可有效應對異常值和寬動態 Y 數據範圍。
