Standard Error of the Regression vs. R-squared

Splet6. Think long and hard about causality. For the R-Squared to have any meaning at all in the vast majority of applications it is important that the model says something useful about causality. Consider, for example, a model that predicts adults' height based on their weight and gets an R-Squared of 0.49.

SpletThe adjusted R-squared increases only if the new term improves the model more than would be expected by chance. It decreases when a predictor improves the model by less than expected by chance. The adjusted R-squared can be negative, but it’s usually not. It is always lower than the R-squared. SpletHowever, model 2 has adjusted R^2 equal to 40 percent, while model 1 has it at 36.8 percent.
