pyhs3.distributions.Distribution

class pyhs3.distributions.Distribution(*, name, kind='Distribution', parameters=None)

Base class for probability distributions in HS3.

Provides the foundation for all distribution implementations, handling parameter management, constant generation, and symbolic expression evaluation using PyTensor.

name

Type:

str

kind

Type:

str

parameters

Type:

list[str]

constants

Generated constants for numeric parameter values.

Type:

dict[str, T.TensorVar]

Parameters:

• name (str)

• kind (str)

• parameters (list[str] | None)

__init__(*, name, kind='Distribution', parameters=None)
