Distributions
=============
Distribution objects represent probability distributions, they have
two principle uses:
1. Samples can be generated from a distribution by passing a
distribution object to the :ref:`sample <sample>` operator.
2. The logarithm of the probability (or density) that a distribution
assigns to a value can be computed using ``dist.score(val)``. For
example::
Bernoulli({p: .1}).score(true); // returns Math.log(.1)
Several :ref:`primitive distributions <primitive-distributions>` are
built into the language. Further distributions are created by
performing :ref:`marginal inference <inference>`.
