prophys.domain

The domain layer: named uncertain quantities, models and observations.

RandomVariable injects a named source of uncertainty into any expression. UncertainAttribute is a documented model output with a unit. ProbabilityModel bundles attributes for compilation. Observations carries measured data, including censored, interval and missing records.

Classes

UncertainAttribute	A named, documented uncertain quantity, the primary unit of meaning in prophys.
AttributeInteractions	Joint dependence between several UncertainAttribute objects, for attributes that are not independent.
ProbabilityModel	A probabilistic model: a collection of UncertainAttribute objects, optionally coupled.
Observations	A set of observations of one attribute, each with its own kind.
RandomVariable	A named source of uncertainty inside an expression, backed by a Distribution.
JointRandomVariable	A vector valued random variable whose named components are jointly distributed.
JointComponent	One named component of a JointRandomVariable.

Functions

find_random_variables	Collect all distinct RandomVariable leaves reachable from expr, keyed by name.
as_observations	Coerce a plain array into exact Observations, returning an Observations unchanged.
