Web21 Mar 2024 · The interpretation of standardized regression coefficients is non-intuitive compared to their unstandardized versions: For example, a 1 standard deviation unit increase in X will result in β standard deviation units increase in y. A change of 1 standard deviation in X is associated with a change of β standard deviations of Y. WebAnd to make that even more confusing, sometimes instead of beta-hat, those sample estimates are denoted B or b. Standardized Regression Coefficient Estimates. But, for some reason, SPSS labels standardized regression coefficient estimates as Beta. Despite the fact that they are statistics–measured on the sample, not the population. More ...
