摘要
本文讨论了投影追踪方法(PP方法),它是一种稳健而又实用的方法,能够帮助揭露高维观测数据的结构。我们应用了PP多元回归、PP主分量分析和PP判别分类方法于地球物理问题的研究,而且作了一些试算以减少计算机CPU的时间。
The projection pursuit(PP) technique is discussed. It is a robust and practical method, and can help uncover the structure of a set of multivariant observations. We apply PP regression, PP principal components and PP classification to the geophysical problem, and make some test calculations to reduce the CPU time.
