該程式基於強大的無模型時間序列分析方法 Caterpillar（另一個名字是 SSA - 單數頻譜分析）。它結合了其他方法的優點和可視化控制輔助工具的簡單性。用於分析一維時間序列的基本 Caterpillar-SSA 演算法包括通過延遲過程將一維時間序列轉換到軌跡矩陣（這為整個技術命名）;軌跡矩陣的奇異值分解;基於若干選定的特徵器重建原始時間序列。Caterpillar-SSA 處理的結果是將時間序列自然分解為多個元件，這些元件通常可以識別為趨勢、季節性和其他振蕩序列或雜訊分量。該方法可以自然地擴展到預測時間序列及其元件，處理多維時間序列和換點檢測。"Caterpillar" 想法在俄羅斯（聖彼德堡、莫斯科）以及英國和美國（以 SSA 的名義，即單一頻譜分析）獨立開發。新書《時間序列結構分析：SSA和相關技術"作者是N.戈利安迪納、V.內克魯特金和A.Zhigljavsky》對SSA一般理論和方法論進行了仔細、清晰的描述（英文，查普曼和霍爾/CRC，見HTTP：//www.gistatgroup.com/cat/）。該方法是氣象學、水文學、地球物理學、氣候學、氣候學、經濟學、生物學、物理學、醫學等科學領域時間序列分析的有力而有用的工具;也就是說，在短和長，一維和多維，固定和非靜止，幾乎確定性和嘈雜的時間序列要分析。我們確信，在不久的將來，與卡特彼勒一樣的方法將躋身於時間序列分析的基本方法之一，並將包含在標準統計軟體中。
