Summary

Quadratic model

Extended Summary

This model is defined by $y = β_{0} x^{2} + β_{1} x + β_{2}$

Examples

We can calculate orthogonal distance regression with a quadratic model:

from scipy import odr
import numpy as np
x = np.linspace(0.0, 5.0)
y = 1.0 * x ** 2 + 2.0 * x + 3.0
data = odr.Data(x, y)
odr_obj = odr.ODR(data, odr.quadratic)
output = odr_obj.run()
print(output.beta)
