Finding coefficient of determination

WebApr 26, 2024 · The coefficient of determination is simply one minus the SSR divided by the SST. R^2 = 1- \frac {SSR} {SST} R2 = 1 − SST SSR Note that R2 could theoretically be smaller than zero if the SSR is larger than the SST. This is possible if the regression line goes against the trend.
