A regression analysis of mortality can benefit from the introduction of certain apparently redundant factors. Following a description of the method of calculating the regression coefficients, data on mortality from breast cancer in England and Wales for 1951-1970 are analysed as a function of age group, quinquennium of birth and quinquennium of death.
死亡率的回归分析可以从引入某些看似冗余的因素中受益。在描述了计算回归系数的方法之后,将1951年至1970年英格兰和威尔士乳腺癌死亡率数据作为年龄组、出生五年期和死亡五年期的函数进行分析。
