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__ (inherited documentation)
