covariation,英語單詞,主要用作名詞,作名詞時譯為“[數] 共變;[遺] 相關變異”。
共變(Covariation),數學術語,根據統計信號分析的二階矩理論,兩個隨機變數的協方差的概念是十分重要的。實際上,信號預測理論,濾波理論,平滑理論以及大多數信號處理的統計理論和方法都是建立在協方差基礎上的。然而,由於SαS分布沒有有限的方差,所以不存在協方差。於是,一個稱為共變(Covariation)的概念於1978...

據性狀的相關變異(covariation),或者是以某些經驗性指導原則為根據。由推論而 知的共同祖先的後存幾乎毫無例外地可以由共同具有某些性狀而查知,因而對一些性狀 較之其他性狀予以更大的加權就是一種常識。任何分類方法不運用性狀加權顯然是無效 的。為了力求“絕對客觀”,數值分類學派完全不考慮任何親緣證據,而與之...
海德還指出,在歸因的時候,人們經常使用兩個原則:一是共變原則(Principle of covariation),它是指某個特定的原因在許多不同的情境下和某個特定結果相聯繫,該原因不存在時,結果也不出現,我們就可以把結果歸於該原因,這就是共變原則。比如一個人老是在考試前鬧彆扭、抱怨世界,其他時候卻很愉快,我們就會把...
