１多元线性回归分析简介直线回归和曲线回归是研究１个因变量和１个自变量之间的关系。但实际上，某种病虫种群数量的消长，常常是多个影响因子相互作用的结果。如害虫发生量往往与虫口基数、寄主植物和外界环境等多个因素有关。多元线性回归就是研究这类１个因变量和多个自变
1 Multivariate linear regression analysis Introduction Linear regression and curve regression is the study of one dependent variable and one independent variable relationship. In practice, however, the growth and decline in the population of some pests and diseases is often the result of the interaction of multiple influencing factors. Such as insect pests often occur with the insect population base, host plants and the external environment and many other factors. Multivariate linear regression is to study such a dependent variable and multiple self-transformation
