| 摘 要： | 本文对煤矿百万吨死亡率关于其影响因素作回归线性假设,以美国1982～1991十年间的煤矿死亡事故数据为例,利用SPSS多元统计软件中的逐步回归分析法,拟合出百万吨死亡率关于所选出的两个显著影响因子的二元线性回归方程,结果表明该方程通过了各项假设检验,可用于百万吨煤死亡率的预测与控制.

| Abstract: | Based on the assumption of linear regression of the million tons death rate about relative factors in coal mine and taking the example of the death data between 1982 and 1991 in America, this paper generates the dualistic linear regression equation of million tons death rate about its two noble factors. And the result indicates that all the assumptions of the regression equation are reasonable. So the application of the regression equation to predict and control the million tons death rate in coal mine is feasible. |
