scipy.odr.exponential

scipy.odr.exponential = <scipy.odr._models._ExponentialModel object>

Exponential model

This model is defined by \(y=\beta_0 + e^{\beta_1 x}\)

Examples

We can calculate orthogonal distance regression with an exponential model:

>>> from scipy import odr
>>> x = np.linspace(0.0, 5.0)
>>> y = -10.0 + np.exp(0.5*x)
>>> data = odr.Data(x, y)
>>> odr_obj = odr.ODR(data, odr.exponential)
>>> output = odr_obj.run()
>>> print(output.beta)
