| 摘 要： | 基于Fisher判别准则建立了沉积环境判别与分类的Fisher判别分析模型。模型选用粒度的平均粒径、标准偏差、偏差以及峰值等4个指标作为判别因子,利用方差分析的思想选择判别系数建立相应的判别函数,以该函数计算待判样品的Fisher判别函数值,以最大值对应的总体作为样品的归属。判别结果表明,所建立的沉积环境判别与分类的Fisher判别模型具有一定的实用价值。

| Abstract: | Based on the principle of Fisher discriminant analysis,the Fisher discriminating analysis model is established to classify the sedimentary environment.Size parameters,such as average size,standard deviation,deviation,peak value are used as the four discriminant factors.Fisher discriminant functions obtained through training samples are used to compute the Fisher functions values of the evaluated samples,and the maximal function value is used to judge which population the sample belongs to.The study shows th... |
