摘要
本文通过实例分析,讨论了对回归方程作回归显著性的F-检验时,如何用拟合不足平方和来检验回归模型的合理性,这对于林业实际工作具有一定的积极意义。
Through actual examples, this paper discusses how to lest the rationality of regression model with the sum of squrc of dcficcncy of fit, when the significance of regression equation is checked with F- test. This has some significance to forestry practice.
