WebJan 5, 2014 · Fit to Gaussian with errors. Hi, I'd like to fit a Gaussian to a set of x,dx,y,dy data, but am unable to do so. Would truly appreciate some assistance. It should be noted that I'd like the fit to not only yield the values for sigma and mu, but also give me the value of kai squared reduced and p-value for that fit! How could it be done? WebApr 11, 2024 · After you fit the gaussian process model, for each value of x, you do not predict a single value of y. Rather, you predict a gaussian for that x location. You predict N(y_mean,y_sigma). In effect, you have made two predictions: A prediction of y_mean, and a prediction of y_sigma. There is uncertainty in both of those predictions.

The fitting function has a form of a*exp (- ( (x-b)/c)^2)+d*x+e. This means the curve is build up a line and a gaussian. INPUTS: "x,y" is input data. "init" is initial guess for parameteres [a b c d e]. marriott hotels in tomball texas
