source_dj
(dj=None, dn=None, ptype=<class 'int'>, lam=1.0, y=None)¶ Set up a source of compound Poisson process increments (jumps), to be used as ‘dj’ during integration.
Parameters: - dj : source, or source subclass, or None
If an object complying with the
source
protocol, it is returned (ptype
,lam
andy
, as well asself.dtype
andself.rng
, are ignored). If a source subclass, it is instantiated with the given parameters, and returned. If None, a new instance ofcpoisson_source
is returned, with the given parameters.- ptype, lam, y : see
cpoisson_source
documentation
Returns: - An object complying with the
source
protocol, - instantiating the requested stochasticity source.
- The shape and paths of source values are set to
self.paths
,self.wshape
respectively.- If instantiated,
dtype=self.dtype
andrng=self.rng
- keywords are used upon instantiation.
