Mean Residual

The Mean Residual is calculated as the average of the absolute residuals.

If the experimental data y_j measured at the points x_j for the curve i, and the model function f(x) is calculated at these points, then the regression values are f(x_j).

The residual between the experimental value and model value for i^thcurve is y_i,j – f(x_i,j).

The Mean Residual (MR) is

where nPoints_i is the number of points in the i^th curve.

If the model curve is drawn exactly through the experimental points, then all Residuals are zero and MR is zero, too.

The closer the calculated model curve is to the experimental data, the closer is MR to zero.
