R2 is famous for its fountain simulation. This piece is about grace and color mixing.
One of the greatest misconceptions regarding $R^2$ is the equation of correlation with causation. A high coefficient tells us that two variables move together, but it is silent on the mechanism of their dependence. Consider the classic example of ice cream sales and drowning incidents. A regression model might yield a high $R^2$, suggesting a strong statistical dependence. Yet, the relationship is spurious; both are dependent on a third variable—temperature. By prioritizing the score over the logic of dependence, analysts risk building models that are mathematically robust but logically bankrupt.
While correlation explains the strength of a relationship between two variables, R-squared explains the extent to which the variance of one variable explains the variance of the second variable.
