Example 8.14: generating standardized regression coefficients. Standardized (or beta) coefficients from a linear regression model are the parameter estimates obtained when the predictors and outcomes have been standardized to have variance = 1. Alternatively, the regression model can be fit and then standardized post-hoc based on the appropriate standard deviations.
Because of their different value meanings and bounds, the formulas are different. From Wikipedia, the correlation coefficient is. where X is the stock return and Y is the market return. Beta is defined as. which is equivalent to. where r_a is the stock return and r_b is the market return. In practice we use beta because it is volatility of a security relative to the benchmark. Correlation does not distinguish which we are studying with respect to the other.
