摘要
分析了回归分析方法在地震科学应用中存在的问题,提出了按变量之间的物理关系进行分类回归的新观点。针对实际地震问题给出了具体的分类方案,从理论上论述了不同类型问题采用不同的回归方法的必要性。通过对实际地震问题分析,剖析了现有回归分析方法的优缺点和适用条件。在此基础上,对不同类型统计问题如何选用适当的回归分析方法提出了合理的建议。
In this paper, we firstly analyze the problems existing sive analysis method to the seismic sciences, and bring forward the in the application of regresviewpoint of classifying the regressive analysis methods according to the physical relationship of variables. Then, we present a detailed scheme of classification for the practical seismic problems, and theoretically discuss the necessity that different regression methods should be adopted for the different kinds of issues. Finally, we dissect the merit and demerit and applicability of existing regressive analysis methods by analyzing the practical seismic problems. On the basis of the study above, we put up with a reasonable suggestion about how to choose the proper regression methods for different kinds of statistical issues.
