pymc.Laplace#
- class pymc.Laplace(name, *args, rng=None, dims=None, initval=None, observed=None, total_size=None, transform=UNSET, **kwargs)[source]#
Laplace log-likelihood.
The pdf of this distribution is
\[f(x \mid \mu, b) = \frac{1}{2b} \exp \left\{ - \frac{|x - \mu|}{b} \right\}\](Source code, png, hires.png, pdf)
Support
\(x \in \mathbb{R}\)
Mean
\(\mu\)
Variance
\(2 b^2\)
- Parameters
- mutensor_like of
float
Location parameter.
- btensor_like of
float
Scale parameter (b > 0).
- mutensor_like of
