This calculator determines the residual sum of squares (SSE) for a given regression model from the predictor and response values.

- Enter the list of predictor and response (observed) values.
- Make sure the inputted list should be comma or space separated.
- Press the 'Calculate' button to obtain the residual sum of squares (SSE) result.

SSE = Σ(y_{i} - ŷ_{i})^{2}

Where,

y_{i} = Observed value,

ŷ_{i} = Predicted value.
