"WebFeb 2, 2016 · Just as a side note, a general 2D guassian has 6 parameters, so you won't be able to fully fit things with 4 points. However, it sounds like you might be assuming that there's no covariance between x and y and that the variances are the same in each direction (i.e. a perfectly "round" bell curve).

One neat feature of the Gaussian distribution is that any linear combination of normally distributed random variables is itself normally distributed. … WebThe fitter function. Single-fitters should take npars + 1 input parameters, where the +1 is for a 0th order baseline fit. They should accept an X-axis and data and standard fitting-function inputs (see, e.g., gaussfitter). Multi-fitters should take N * npars, but should also operate on X-axis and data arguments.
