After training, you can predict a value by calling polyfit, with a new example. It will then output a continous value. Example. The example below plots. In python, Numpy polyfit () is a method that fits the data within a polynomial function. That is, it least squares the function polynomial fit. For example, a polynomial p (X) of deg degree fits the coordinate points (X, Y). This function returns a coefficient vector p that lessens the squared error in the deg, deg-1,0 order.

The function NumPy.polyfit () helps us by finding the least square polynomial fit. This means finding the best fitting curve to a given set of points by minimizing the sum of squares. It takes 3 different inputs from the user, namely X, Y, and the polynomial degree. Here X and Y represent the values that we want to fit on the 2 axes.
