The model function, f(x, ). It must take the independent variable as the first argument and the parameters to fit as separate remaining arguments.

Curve Fitting scipy.optimize.curve_fit First, we have to import curve_fit from scipy.optimize. curve_fit is using “least squares method” to optimize the curve. it will mininize $\sum_i[f(x_i,

If False, sigma denotes relative weights of the data points. The returned covariance matrix pcov is based on estimated errors in the data, and is not affected by the overall

Robust curve fitting methods, such as those available in the scipy.optimize.curve_fit() function, This can guide you in refining the curve fitting approach.

You need to define the points you want to fit, i.e. defining x and y before calling curve_fit(). I have two numpy arrays x and y and would like to fit a curve to the data. The fitting
