在《机器学习---最小二乘线性回归模型的5个基本假设(Machine Learning Least Squares Linear Regression Assumptions)》一文中阐述了最小二乘线性回归的5个基本假设以及违反这些假设条件会产生的后果。那么,我们怎么检测出是否有违反假设的情况出现以及如何解决出现的问题呢?(注:内生性的问题比较复杂,这里暂时略过。) ...
Results from GLR are only reliable if the data and regression model satisfy all of the assumptions inherently required by this method. Review all resulting diagnostics and consult the Common regression problems, consequences, and solutions table in Regression analysis basics to ensure that the model ...
Caution should be exercised here to not get confused just because gradient descent is deployed in all these formulations, the intuition behind the approaches are different between regression and classification problems. In case of neural networks, one often finds solving regression problems for each ...

Linear regression models, in general, are among the most commonly used statistical methods, while multivariate regression models extend the basic idea to many response variables. The theory behind multivariate linear regression modeling is highly developed and easily applied to real problems. Implementation...
The last assumption of the linear regression analysis ishomoscedasticity. The scatter plot is good way to check whether the data are homoscedastic (meaning the residuals are equal across the regression line). The following scatter plots show examples of data that are not homoscedastic (i.e., hete...
