It is calculated as one minus the ratio of the sum squared regression (SSR) to the total sum of squares (SST).

The sum squared regression represents the sum of the squared differences between the observed values and the predicted values from the regression model.

The total sum of squares, on the other hand, is the sum of the squared differences between the observed values and the mean of the observed values.

In mathematical terms, R 2 is expressed as 1 minus the sum of squared residuals divided by the sum of squared deviations from the mean.
