popsynth.aux_samplers.trunc_normal_aux_sampler module

class popsynth.aux_samplers.trunc_normal_aux_sampler.TruncatedNormalAuxSampler(name: str, observed: bool = True)

Bases: popsynth.auxiliary_sampler.AuxiliarySampler

__init__(name: str, observed: bool = True)

A truncated normal sampler, where property ~ N(mu, sigma), between lower and upper.

Parameters:

• name (str) – Name of the property
• observed (bool) – True if the property is observed, False if it is latent. Defaults to True
• mu (AuxiliaryParameter) – Mean of the normal
• tau (AuxiliaryParameter) – Standard deviation of the normal
• lower (AuxiliaryParameter) – Lower bound of the truncation
• upper (AuxiliaryParameter) – Upper bound of the truncation
• sigma (AuxiliaryParameter) – Standard deviation of normal distribution from which observed values are sampled, if observed is True
