In statistics the residual sum of squares RSS also known as the sum of squared residuals SSR or the sum of squared estimate of errors SSE is the sum of the squares of residuals In regression analysis the sum of squares SS is particularly helpful because it separates variability into three types total SS regression SS and error SS After explaining them
To calculate SSR for simple linear regression models follow these steps 1 Determine your regression equation Obtain the equation that captures your response y and predictor The following formula shows how SSR is calculated where n is the total observation number NOTE We calculate vertical distance to the line SSR is a good way to evaluate a
