# 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
      >>> import numpy as np
      >>> 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)
      [-10.    0.5]
