對應分析(Correspondence Analysis, CA)是一種探索分類變量間關系的多元統計可視化技術,尤其適用于分析列聯表(交叉表)數據。其核心思想是将行和列的類别表示為低維空間(通常是二維平面)中的點,通過點之間的距離來揭示它們之間的關聯模式。

對應分析(Correspondence Analysis)是一種多元統計技術,主要用于分析分類變量構成的列聯表(contingency table),揭示變量類别之間的關聯關系。其核心思想是将行和列類别映射到低維空間(如二維坐标系)進行可視化分析。
① 構建列聯表 → ② 标準化處理 → ③ 計算慣量(Inertia) → ④ 坐标軸提取 → ⑤ 結果可視化
對于$m×n$列聯表$F=(f{ij})$,标準化殘差矩陣計算為: $$ Z = frac{f{ij} - frac{r_ic_j}{N}}{sqrt{r_ic_j/N}} $$ 其中$r_i$為行合計,$c_j$為列合計,$N$為總樣本量。
該分析方法特别適用于探索性數據分析,但需注意其假設數據滿足獨立性檢驗。實際應用中常結合聚類分析等方法進行綜合研究。
