Copy. xobs = repelem (x,y); You need to estimate the parameters of the best-fitting Gumbel for this set of xobs values. The maximum-likelihood estimates of the two parameters are 1.8237,0.86153, according to Cupid (where the Gumbel distribution is called ExtrVal1).

Will a solution be to export peaks into a new array, plot them and then create a fitting curve or there is another way? Thanks in advance! Sign in to comment. WebSep 25, 2024 · I have tried using polyfit, smoothingspline, pchip and other curve-fitting tools, but all of them connect the wrong data points together, since this graph is actually x = f(y). In MS Excel, if I switch the axes so the curve becomes a one-to-one function where y = f(x), I can easily fit a quadratic curve to the points.
Webplot (sfit) plots the sfit object over the range of the current axes, if any, or otherwise over the range stored in the fit. plot (sfit, [x, y], z) plots z versus x and y and plots sfit over the range of x and y.
