WebI would like to fit a curve to this data, using mixtures of one to five Gaussians. In Matlab, I could do the following: fits {1} = fit (1:length (x),x,fittype ('gauss1')); fits {2} = fit (1:length (x),x,fittype ('gauss2')); fits {3} = fit (1:length (x),x,fittype ('gauss3')); ... and so on. In R, I am having difficulty identifying a similar method.

But now you want to find a mean and standard deviation. A problem is there is no presumption that the curve you have actually integrates to 1. So that tells me the parameter a1 is useless. WebGaussian fits have the width parameter c1 constrained with a lower bound of 0. The default lower bounds for most library models are -Inf, which indicates that the coefficients are unconstrained.
