Residual Sum of Squares Calculator. This calculator finds the residual sum of squares of a regression equation based on values for a predictor variable and a response variable. Simply enter a list of values for a predictor variable and a response variable in the boxes below, then click the “Calculate” button:The sum of the median x values is 206.5, and the sum of the median y values is 476. Substituting these sums and the slope into the formula gives b = 476 − 6.9 ( 206.5) 3 , which simplifies to b ≈ − 316.3 . The line of best fit is represented as y = m x + b . Thus, the equation can be written as y = 6.9 x − 316.3. Linear regression is used to model the relationship between two variables and estimate the value of a response by using a line-of-best-fit.
