pymc.backends.base.BaseTrace

class pymc.backends.base.BaseTrace(name, model=None, vars=None, test_point=None)

Base trace object.

Parameters:

name: str

Name of backend

model: Model

If None, the model is taken from the with context.

vars: list of variables

Sampling values will be stored for these variables. If None, model.unobserved_RVs is used.

test_point: dict

use different test point that might be with changed variables shapes

BaseTrace.point(idx)	Return point values at idx for current chain.
BaseTrace.record(draw, stats)	Record results of a sampling iteration.
BaseTrace.setup(draws, chain[, sampler_vars])	Perform chain-specific setup.

Attributes
