UnverifiedMulticollinearity refers to the situation where two or more independent variables are highly linearly correlated, causing the model to be unable to stably distinguish the independent contribution of each variable.77% similarUnverifiedRidge Regression is a regression algorithm that adds an L2 regularization term on top of ordinary linear regression, penalizing model coefficients while minimizing prediction error to prevent overfitting.77% similarUnverifiedWhen a linear relationship is observed in data, one should not immediately conclude that the underlying mechanism is linear.76% similarUnverifiedThe coefficients of linear regression are essentially the weights in the model formula and require no additional conversion.71% similarUnverifiedWhen the dependent variable is a continuous numerical value, linear regression is a reasonable starting point with strong interpretability.71% similar
