电子计算机的出现,给地球化学多元统计方法的应用,开辟了广阔的前景。然而,它只是速度快、精确度高的计算工具,并不能替代用数理统计方法研究解决多指标的理论问题,对于研究课题和工作任务,它也不能提出问题和进行解释。因此,对于多元统计方法的本身,甚至涉及到样品采集、数据处理,都还必须以数理统计的理论基础,结 The advent of electronic computers has opened up broad prospects for the application of multivariate statistical methods of geochemistry. However, it is only a fast and accurate computational tool, and it can not replace mathematical theory to solve the theoretical problem of solving multiple indicators. It also can not ask questions and explain the research tasks and tasks. Therefore, for multivariate statistical methods themselves, even involving sample acquisition, data processing, must also be the theoretical basis of mathematical statistics, knot
