  1. Mean, variance, standard deviation, coefficient of variation of fourteen vital morphological characters indicated that great diversity existed either among species or among populations, with cv ranging from 28. 89 - 122. 36 % ( except dtm, which has a cv of 4. 72 % ). correlation analysis indicated that il showed a significant positive correlations with pfk ll and lw ( p < 0. 05 ), but a negative correlation with nm ( p < 0. 05 ). there were also strong positive correlations between each other of ll, lw, la and sw

  2. In samcluster system, the following cluster methods including hierarchical cluster analysis. k - means, and self - organizing map ( som ) and the feature selection methods based on coefficient of variation ( cv ) and simple t - test were integrated. to evaluate the performance of the samcluster system, the samcluster was applied to four expression datasets colon, leukemia72

    在samcluster系統中,整合了下列聚類演算法:譜系聚類、 k -平均值聚類和自組圖聚類與變異系數計算和t -檢驗等基因變量選擇方法,並提出了一致的樣本分型概念,通過對四個基因表達譜的數據集colon 、 leukemia72 、 leukemia38和ovarian的測試,結果表明:誤判的樣本數分別為5 、 1 、 0和0個,因此,基因水平的樣本分型與樣本的臨床分型高度一致。
