Results -- Displays detailed results for the current fit including the fit type (model, spline, or interpolant), the fitted coefficients and 95% confidence bounds for parametric fits, and these goodness of fit statistics:
SSE -- The sum of squares due to error. This statistic measures the deviation of the responses from the fitted values of the responses. A value closer to 0 indicates a better fit.
R-square -- The coefficient of multiple determination. This statistic measures how successful the fit is in explaining the variation of the data. A value closer to 1 indicates a better fit.
Adjusted R-square -- The degree of freedom adjusted R-square. A value closer to 1 indicates a better fit. It is generally the best indicator of the fit quality when you add additional coefficients to your model.
RMSE -- The root mean squared error. A value closer to 0 indicates a better fit.
