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. WebIf we do the same thing for females, we get 35/74 = .47297297. To get the odds ratio, which is the ratio of the two odds that we have just calculated, we get .47297297/.24657534 = 1.9181682. As we can see in the output below, this is exactly the odds ratio we obtain from the logistic command.
