pymc.step_methods.DEMetropolisZ.__init__

DEMetropolisZ.__init__(vars=None, *, S=None, proposal_dist=None, lamb=None, scaling=0.001, tune='scaling', tune_interval=100, tune_drop_fraction=0.9, model=None, initial_point=None, compile_kwargs=None, mode=None, rng=None, blocked=True)

Create the ArrayStepShared object.

Parameters:

vars: list of sampling value variables

shared: dict of PyTensor variable -> shared variable

blocked: Boolean (default True)

rng: RandomGenerator

An object that can produce be used to produce the step method’s Generator object. Refer to pymc.util.get_random_generator() for more information.
