从70年代开始,随着微机的普及、推广,多元统计分析方法及其他数值分析方法在各个领域得到越来越广泛的应用。这就产生了两种要求:一是系统总结多元统计分析方法理论和应用情况,评价它在林业中应用的可能及前途;二是要为微机配置一套通用程序,使林业工作者从繁重的计算工作中解放出来,使多元统计分析方法付诸实施,也有利于多元统计分析
Since the 1970s, with the popularization and popularization of microcomputer, multivariate statistical analysis methods and other numerical analysis methods have been applied more and more widely in all fields. This creates two requirements: First, systematically summarize the theory and application of multivariate statistical analysis method to evaluate its possible and future application in forestry; second, configure a common set of procedures for microcomputer to enable forestry workers to work hard from the heavy The liberation of the calculation work, so that the implementation of multivariate statistical analysis, but also conducive to multivariate statistical analysis
