五、多元线性回归方法的计算程序上一节介绍的一元线性和非线性回归分析计算程序,仅仅适用于计算两个变量之间的关系。在种质资源研究中往往需要我们同时考虑两种或两种以上的变量间的关系。例如,在研究小麦矮源时,不仅研究株高与单株粒重之间的关系,还要研究株高与穗长、粒数、千粒重之间相互制约的关系。在研究种子贮藏生理时,对种子活力的评价,不 V. Multiple Linear Regression Calculation Procedures The unary linear and non-linear regression analysis and calculation procedures introduced in the previous section are only suitable for calculating the relationship between two variables. In germplasm research, we often need to consider the relationship between two or more variables at the same time. For example, when researching the dwarf source of wheat, we not only studied the relationship between plant height and grain weight, but also studied the relationship between plant height and spike length, grain number and 1000-grain weight.
