Tsou (2003) 利用 Royall & Tsou (2003) 的強韌概似函數的方法,提出了比較兩個母體變異數的強韌推論法。主要便是依據常態分配作為實作模型,並利用修正後的強韌概似函數產生的概似比統計量。而此強韌概似比統計量比Tiku & Balakrishnan (1984) 的方法更具穩健性。
本文主要是推廣Tsou (2003) 的強韌法,針對三個或更多母體變異數的比較問題,提出有母數的強韌分數統計量。同時將此強韌分數統計量和Bartlett (1937) 以及 Tiku & Balakrishnan (1984) 所提出的統計量做比較。
研究發現,在樣本數大的時候,不論真正的分配為何,只要它們具有四階的動差,利用修正後的強韌分數統計量能得到正確的參數推論結果。
