WebThe Gaussian model fits peaks, and is given by. y = ∑ i = 1 n a i e [ − ( x − b i c i) 2] where a is the amplitude, b is the centroid (location), c is related to the peak width, n is the number of peaks to fit, and 1 ≤ n ≤ 8. Gaussian peaks are encountered in many areas of science and engineering. For example, Gaussian peaks can ... WebThis is especially true if the coefficients are not constrained: with the forms of the two terms being the same, exchanging the three model parameters between the two terms gives you the same function value, so the fitting cannot possibly decide whether (for example) it is the first term or the second term that should be multiplied by 0.83.
