CalcGaussFit 

The procedure CalcGaussFit calculates the best fitting Gaussian curve (normal distribution) 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, k1, and k2 are estimated by CalcGaussFit using a least squares approximation. 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 CalcGaussFit. Do not forget to reset the statistics calculation before entering any new data sets (use the method Init) In addition to the parameters k0, k1, and k2 CalcGaussFit returns the goodness of fit FitQual. This parameter may vary between 0.0 and 1.0, indicating the best possible fit if FitQual equals 1.0.
