The procedure CalcExponentialFit calculates the best fitting exponential curve for a given set of data. The curve is determined by the equation
The values of x and y are given by the data samples, the parameters k0 and k1 are estimated by CalcExponentialFit using a least squares approximation. An exception is raised if the fit cannot be calculated (i.e. if the xvalues are too
large).
The data points [x,y] have to be entered using the routine EnterStatValue. A minimum number of 3 values is required in order to apply CalcExponentialFit. Do not forget to reset the statistics calculation before entering any new data sets (use the method Init).
In addition to the parameters k0 and k1, CalcExponentialFit calculates the quality of fit FitQual. This parameter may vary between 0.0 and 1.0, indicating the best possible fit if FitQual equals 1.0.
