WebFeb 22, 2024 · Using SSR and SST, we can calculate R-squared as: R-squared = SSR / SST. For example, if the SSR for a given regression model is 137.5 and SST is 156 then we would calculate R-squared as: R-squared = 137.5 / 156 = 0.8814. This tells us that 88.14% of the variation in the response variable can be explained by the predictor variable. WebLets say you have a equation that says y=1/4x+2. Its pretty simple from there.
