How do you fit a polynomial?
To perfectly fit a polynomial to data points, an order polynomial is required. To restate slightly differently, any set of points can be modeled by a polynomial of order . It can be shown that such a polynomial exists and that there is only one polynomial that exactly fits those points.
How do you fit a polynomial data in Python?
To get the least-squares fit of a polynomial to data, use the polynomial. polyfit() in Python Numpy. The method returns the Polynomial coefficients ordered from low to high. If y was 2-D, the coefficients in column k of coef represent the polynomial fit to the data in y's k-th column.
How many points does a polynomial fit?
A line will connect any two points, so a first degree polynomial equation is an exact fit through any two points with distinct x coordinates. This will exactly fit a simple curve to three points.
