求翻译：为了找到因素之间的关系是否为线性关系，我们对收集的数据，运用决策分析的方法对影响因素数据进行相关分析：I 通过分析各个因素数据之间的相关关系，得到数据之间为正相关或负相关、各个因素之间的显著性水平。II 根据需求再剔除一些其它因素，运用判别分析得到准确的相关关系。III 根据回归分析的显著性检验，得出各个因素之间的回归方程，通过方程显示各个因素之间的方程关系，找出对影响居民生活质量最大的因素，进行曲线估计，会得到相关的预测值及预测区间。是什么意思？

To find the relationship between the factors for the linear relationship, we collect data, use the method of decision analysis on the impact factor data: i by analyzing the relationship between various factors data, get data between the positive related or negatively correlated, the significance lev
