Average RF fit

Average RF formula:

y = a * x

where
a	Slope

The application first calculates the response factor (RF) for each calibration sample. Then, all response factors are averaged. The Average RF is indicated in the calibration curve legend and corresponds to the slope of the line.

The y-intercept is always zero, as the force origin option is automatically used. The weighting method is automatically set to None.

With the Average RF fit, r and R² are not relevant and not calculated.
