WebUse non-linear least squares to fit a function, f, to data. Assumes ydata = f (xdata, *params) + eps. Parameters: fcallable The model function, f (x, …). It must take the independent variable as the first argument and the parameters to fit as separate remaining arguments. xdataarray_like The independent variable where the data is measured. Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data. A related topic is regression analysis, which focuses more on questions of statistical inference such as how much uncertainty is present in a curve tha… stay in vase flower holder https://pixelmotionuk.com
