摘要:
本文以东海、黄海带鱼分类为实例,介绍了协方差分析在鱼类分类中应用的依据、条件和方法。作者认为,与生长有关的计量分类指标经相关检验后,可使用协方差分析方法消除生长对分类指标的影响,在统一的水平下考查两类间指标均值的差异性。

THE APPLICATION OF COVARIANCE ANALYSIS IN RESEARCH OF THE CLASSIFICATION OF LARGEHEAD AIRTAIL IN THE YELLOW AND EAST CHINA SEAS
Abstract:
For the classification of largehead airtail in the Yellow and East China Sea, this paper introduces the covariance analysis to the classification. The writer holds that covariance analysis can be used to classfy the indexes in correlation with growth. This method can eliminate the disturbance brought up by growth, and make clear the variance between two group means under a unified level.
