Econometrics is sometimes criticized for relying too heavily on the interpretation of regression output without linking it to economic theory or looking for causal mechanisms. It is crucial that the findings revealed in the data are able to be adequately explained by a theory. Calculating Regression ...
在linear regression中讲了线性回归,并且采用了least-squares cost function J(θ)=12∑i=1mhθ(x(i)−y(i))2 ,那么为什么这样的解决方案是有效的,本文将在、给定一系列概率假设的情况下,来解释最小二乘回归为什么是一个很自然的算法 1. 概率假设 我们假设目标变量和输入之间的关系为 y(i)=θTx(i)+...
8. 模型诊断（Model Diagnostics）：在加权回归分析中，模型诊断是一个重要步骤，用于检查模型假设是否得到满足，包括检查权重的选择是否适当。9. 预测和解释（Prediction and Interpretation）：加权回归模型可以用来进行预测，并解释自变量对因变量的影响。然而，由于权重的引入，解释回归系数时需要更加谨慎。加权回归分析...
虽然这似乎并没有损害它的预测能力，但它并不是解释(interpretation)的目的，特别是当变量p的数量很大时。
Next, we discuss the different interpretation of coefficients from randomized experiments and from observational studies. The normal distribution plays a central role in regression, and the coefficients assuming normality are also discussed. The... S Weisberg - Applied Linear Regression, Third Edition 被...
A framework is developed for the interpretation of regression plots, including plots of the response against selected covariates, residual plots, added-variable plots, and detrended added-variable plots. It is shown that many of the common interpretations associated with these plots can be misleading....

The plot really brings this to life. However, plots can display only results from simple regression—one predictor and the response. For multiple linear regression, the interpretation remains the same. Contour plots can graph two independent variables and the dependent variable. For more information,...

2. 概率解释(Probabilistic interpretation) 在本节中将会解释为什么选择线性回归模型,以及为何使用最小二乘法最为成本函数。 首先咱们假设目标变量和输入值存在下面这种等量关系: y^{(i)}=\theta^T x^{(i)}+ \epsilon ^{(i)} 上式中 $ \epsilon ^{(i)}$ 是误差项,用于存放由于建模所忽略的变量导致的...
