为了保证线性模型的合理性， 首先要分析因变量和自变量之间的相关性，可通过计算简单相关系数分析。 只有与因变量高度相关的自变量才会适合引入线性模型。 因此首先必须做变量间的关系分析，结果如表 1 所示。

結果 (英文) 1:

In order to ensure a linear model is reasonable, we must first analyze the dependent variable and the correlation between the independent variables can be analyzed by calculating the simple correlation coefficient. Only the dependent variable will be highly relevant for the introduction of the independent variable linear model. Therefore, we must first make the relationship between the variables analyzed, the results shown in Table 1.

結果 (英文) 2:

In order to ensure the rationality of the linear model, the first analysis for the correlation between variables and variables, can be calculated by simple correlation coefficient analysis. Only with the dependent variables highly correlated variables will be suitable for introducing the linear model. So we must analysis the relationship among the variables, as shown in table 1.

結果 (英文) 3:

In order to ensure the rationality of the linear model, first analysis of correlations between dependent variable and independent variable, you can calculate simple correlation analysis. Only highly correlated with dependent variable independent variable will be introducing a linear model. Therefore first have to do analysis of the relationships between variables, the results as shown in table 1.
