NestedModel
(outer, inner, *otherargs, **otherkwargs)[source] [edit on github]¶ Bases:
sherpa.models.model.CompositeModel
,sherpa.models.model.ArithmeticModel
Apply a model to the results of a model.
- Parameters
outer (Model instance) – The model to apply second.
inner (Model instance) – The model to apply first.
*otherargs – Arguments that are to be applied to the outer model.
**otherkwargs – Keyword arguments that are to be applied to the outer model.
-

apply
(outer, *otherargs, **otherkwargs) [edit on github]¶
-
calc
(p, *args, **kwargs)[source] [edit on github]¶ Evaluate the model on a grid.
- Parameters
p (sequence of numbers) – The parameter values to use. The order matches the
pars
field.*args – The model grid. The values can be scalar or arrays, and the number depends on the dimensionality of the model and whether it is being evaluated over an integrated grid or at a point (or points).

get_center
() [edit on github]¶
-
guess
(dep, *args, **kwargs) [edit on github]¶ Set an initial guess for the parameter values.
Attempt to set the parameter values, and ranges, for the model to match the data values. This is intended as a rough guess, so it is expected that the model is only evaluated a small number of times, if at all.
-
reset
() [edit on github]¶ Reset the parameter values.
-
set_center
(*args, **kwargs) [edit on github]¶
-
startup
(cache=False)[source] [edit on github]¶ Called before a model may be evaluated multiple times.
- Parameters
cache (bool, optional) – Should a cache be used when evaluating the models.
