scipy.odr.polynomial

scipy.odr.polynomial(order)[source]

Factory function for a general polynomial model.

Parameters:
order : int or sequence

If an integer, it becomes the order of the polynomial to fit. If a sequence of numbers, then these are the explicit powers in the polynomial. A constant term (power 0) is always included, so don’t include 0. Thus, polynomial(n) is equivalent to polynomial(range(1, n+1)).

Returns:
polynomial : Model instance

Model instance.
