Class RWMCPropagator

object --+ | AbstractPropagator --+ | AbstractMCPropagator --+ | RWMCPropagator

Draws a number of samples from a PDF using the RWMCSampler and returns them as a Trajectory.

Method Details

init(self, pdf, stepsize=1.0, proposal_density=None, temperature=1.0)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:

pdf (AbstractDensity) - PDF to sample from
stepsize (float) - Serves to set the step size in proposal_density, e.g. for automatic acceptance rate adaption
proposal_density (callable) - The proposal density as a function f(x, s) of the current state x and the stepsize s. By default, the proposal density is uniform, centered around x, and has width s.
temperature (float) - See documentation of AbstractSingleChainMC

Overrides: object.__init__
