摘要
两栖类动物的活动能力常被作为生态环境监测的重要指标。以中华大蟾蜍为例,利用多元线性回归分析理论以及统计分析工具SPSS对其活动能力进行分析,通过检验回归方程的拟合度,并对其进行F检验、t检验以及残差分析,建立了合理的多元线性回归方程,结果表明方程拟合度好,符合实际情况。多元线性回归分析技术的应用为研究动物活动能力和生态环境监测提供了新的工具和途径。
Activity ability of Amphibian was the important indication of ecological environment.B, gargarizan＇s activity ability was analyzed by using the theory of muhiple linear regress analysis and SPSS software. A reasonable multiple linear regression equation was formulated by testing the fitting degree and conducting F test, t test and residual analysis of the regression equation. The results showed that model established conformed to the reality. Application of the multiple linear regression analysis technology gave a new tool and method on analyzing animal＇s activity ability.
