How to Use the Residuals Calculator?

1. First, input the list of independent (X) and dependent (Y) variables with a comma or space delimiter. Example: 3, 5,10,15 or 3 5 10 15.
2. Press the 'Calculate' button.
3. Finally, the tool returns the linear regression equation (with slope and intercept) and R-squared value for the given regression model.
4. It also shows the list of residuals associated with each observation.
