__init__
(name: str, observed: bool = True)[source]¶ A delta-function sampler for which the true value is fixed at
xp
. Assumes property is observed by default, in which case the observed value is sampled from the true value with some normally-distributed error,sigma
.Parameters: - name (str) – Name of the property
- observed (bool) – True if the property is observed, False if it is latent. Defaults to True
- xp (
AuxiliaryParameter
) – Value at which delta function is located - sigma (
AuxiliaryParameter
) – Standard deviation of normal distribution from which observed values are sampled, ifobserved
is True
