pymc.dims.Laplace#

class pymc.dims.Laplace(name, *dist_params, dims=None, initval=None, observed=None, total_size=None, transform=UNSET, default_transform=UNSET, model=None, **kwargs)[source]#

Laplace distribution.

The pdf of this distribution is

\[f(x \mid \mu, b) = \frac{1}{2b} \exp \left\{ - \frac{|x - \mu|}{b} \right\}\]
