    Stata中的模型诊断图之Residual vs Fitted Plot以及线性回归假设简述

    线性回归是概率统计学里最重要的统计方法, 它实际上是一种参数化的方法, 因而为了达到分析目的, 我们需要对模型设定一些假设. 我们有不同的工具可以用来诊断这些假设是否成立, 从而帮助我们判断线性拟合是否成立. 如果回归分析不满足这些假设, 那么分析的结果就会出现偏差....

    Stata中的模型诊断图之偏残差图以及非线性回归简述

    偏残差图(component plus residual plot)又称成分+残差图, 是在多元回归中常被用来诊断非线性的工具. 它与普通残差图 (residual plot) 的区别在于它用偏残差代替普通残差, 从而构建与预测变量Xi之间的散点图....

    回归模型的设定误差检验 (RESET) 以及Stata里的RESET检验法

    函数形式误设 (functional form misspecification) 是多元回归模型中一个很常见的问题. 如果一个多元回归模型不能正确地解释因变量和所观测到的解释变量之间的关系, 那么这个模型就存在函数形式误设问题. 为了检验模型是否存在函数形式误设的问题,...
