NotImplementedError – must be implemented by the subclass.

abstract classmethod logcdf(*args, **kwargs) → Tensor

Computes the natural logarithm of the cumulative distribution function.

Returns:

log of the resulting cumulative probabilities.

Return type:

torch.Tensor

Raises:

NotImplementedError – must be implemented by the subclass.

abstract classmethod logpmf(*args, **kwargs) → Tensor
