CurveFitter 執行統計回歸分析，以估計線性、多變數、多項式、指數函數和非線性函數的參數值。回歸分析確定使函數最適合您提供觀測數據的參數的值。此過程也稱為曲線擬合。 在幾秒鐘內將數千個資料放入方程中： CurveFitter 使科學家、研究人員和工程師能夠找到最複雜數據的理想模型，包括可能從未考慮過的方程。您可以建構方程集，該方程集可以包括適用於任何應用的線性和非線性模型的廣泛陣列。其最先進的資料擬合包括以下功能： *包含最多 9 個參數和 8 個變數的任何使用者定義的方程。 *線性方程。 *非線性指數、對數和功率方程。 *38 位元精密數學模擬器，用於正確擬合高階多項式和理性。 以圖形方式檢視曲線擬合結果： 數據擬合后，CurveFitter 會根據標準誤差的統計標準自動對擬合方程進行排序和繪製。在「查看曲線擬合」視窗中為所選擬合方程生成殘差圖和參數輸出。 有了所有這些能力，它仍然易於使用： CurveFitter 充分利用 Windows 用戶介面來簡化操作的各個方面 -- 從數據導入到結果輸出。從 txt 格式匯入資料。數據進入編輯器后，創建自定義方程集，只需單擊滑鼠即可啟動自動擬合過程。CurveFitter 非常直觀、易於使用且學習非常簡單。
