class sakkara.model.Likelihood(generator: Callable, observed: DataComponent, name: str = 'likelihood', group: str | Tuple[str, ...] = 'obs', nan_param_mask: Dict[str, Any] | None = None, nan_data_mask: Any | None = None, **kwargs: Any)

Component for a likelihood distribution, e.g, with observed data.

Parameters:

• generator – PyMC callable for distribution to use.

• observed – Data to input as observed keyword in PyMC.

• name – Name of the corresponding variable to register in PyMC.

• group – Group of which the component is defined for.

• nan_param_mask – Masked distribution parameters to use for rows with Nan, must be defined for each keyword argument entered. Required if there are Nan in observed.

• nan_data_mask – Masked observed value to use for rows with Nan. Required if there are Nan in observed.
