摘要
文章通过对大量的生命表数据验证,人口生命基本过程可以用对韦伯函数的幂(常数)经过变异后的函数形式来表示,模型参数可以用线性回归的方法来确定。模型的基本部分加波动部分就组成了人口生命过程的完整模型。人口生命函数的基本部分可以近似地组成一个线性空间,这样,就可以解释人口间接模型在不同场合采用不同参数的意义,并且,从理论上解释了两类模型的统一性。最后,文章还指出了现行的间接模型中采用的Logit变换同两次对数变换可取同一个函数形式。
Basic vital process of population can be expressed by the resolution function, which is transferred from the
exponential (constant) of Web function, after testing and verifying a large number of the data from life table. The
parameters of the model can be determined after regressions. The combination of the basic and random part leads to
the complete model of population vital process. The basic part can be regarded approximately as a linear space, which
can explain the different meanings of parameters in the model under the various circumstances, and the unity of the
two models theoretically. This paper indicates that the same function format can be reached among the logit
transformation, adapted by the indirect estimation at present, and twice logarithm transformations.
