随着我国医学科研的深入发展及电子计算机的普及应用,医学杂志中应用多变量统计分析日趋增多,如我院百名临床硕士研究生的论文中,涉及到多变量问题的约占1/3,其中应用逐步回归分析的又居首位。逐步回归的理论依据是相当充分,但在临床科研应用方面还存在一些问题,值得进一步探讨。下面结合我们在应用逐步回归分析中的一些问题,提出看法与疑问。
With the in-depth development of China’s medical research and the popularization and application of electronic computers, the application of multivariate statistical analysis in medical journals is increasing day by day. For example, in the papers of 100 clinical postgraduates in our hospital, about 1/3 of the problems involving multivariate problems are involved. The application of stepwise regression analysis also ranked first. The theoretical basis for stepwise regression is quite sufficient, but there are still some problems in the clinical research and application, and it is worth further discussion. The following is a combination of our questions in the application of stepwise regression analysis.
