试将新近提出的Ｆｉｓｈｅｒ岭判别分析法用于临床中疾病诊断研究．该法首先算出数据的组内离差阵Ｅ，然后对组内离差阵Ｅ作一类似于岭回归分析中的变换，继而用与经典的Ｆｉｓｈｅｒ判别分析法相同的步骤进行计算．将此方法用于血吸虫病肝硬化与门脉性肝硬化疾病诊断研究，所得结果优于经典的Ｆｉｓｈｅｒ判别分析法．
The newly proposed Fisher ridge discriminant analysis for clinical diagnosis of disease. The method first calculates the in-group dispersion E of the data, and then performs a transformation similar to the ridge regression analysis on the in-group dispersion E, which is then calculated using the same procedure as the classical Fisher discriminant analysis. The method was applied to the diagnosis of cirrhosis and portal cirrhosis in schistosomiasis. The results obtained were better than the classical Fisher discriminant analysis.
