随着生物学、医学研究从定性向定量的发展,各种各样的数学方法、数学模型开始进入生物学、医学的研究领域。但是由于生物学、医学研究对象的极其复杂性,对于大多数问题目前还不能给出确切的数学模型来描述。一般地讲,我们只能给出一些不很确定的数学关系,例如用统计分析方法、模糊数学或经验公式来讨论原因与结果之间的定量关系。于是在人们的心目中可能会产生两个疑问:一是,研究这种不很确切的数学模型有无实际意义?二是,如何评价一种数学模型的好坏?显然这些
With the development of biology and medical research from qualitative to quantitative, various mathematical methods and mathematical models have begun to enter the fields of biology and medicine. However, due to the extremely complex nature of biological and medical research objects, the exact mathematical model cannot be described for most problems. In general, we can only give some uncertain mathematical relationships, such as using statistical analysis methods, fuzzy mathematics, or empirical formulas to discuss the quantitative relationship between causes and results. So two questions may arise in the minds of people: First, is it really meaningful to study this not-so-exact mathematical model? Second, how do you evaluate the quality of a mathematical model? Obviously these
