Intuitively, a Lipschitz continuous function is limited in how fast it can change: there exists a real number such that, for every pair of points on the graph of this function, the absolute value of the slope of the line connecting them is not greater than this real number; the smallest such bound is called the Lipschitz constant of the function (or modulus … ray armfield twitterWebwith sigmoid parameters. x0 = 0.826964424481 y0 = 0.151506745435 c = 0.848564826467 k = -9.54442292024. Note that for newer versions of scipy (e.g. 0.9) there is also the scipy.optimize.curve_fit function which is easier to use than leastsq.
