mu
= Parameter('mu', value=0.0)¶
-
param_names
= ('mu', 'phi0', 'theta0')¶ Names of the parameters that describe models of this type.
The parameters in this tuple are in the same order they should be passed in when initializing a model of a specific type. Some types of models, such as polynomial models, have a different number of parameters depending on some other property of the model, such as the degree.
When defining a custom model class the value of this attribute is automatically set by the
Parameter
attributes defined in the class body.
-
phi0
= Parameter('phi0', value=0.0)¶
-
theta0
= Parameter('theta0', value=0.0)¶
