tracts.demography.base_parametrized_demography

Defines BaseParametrizedDemography, the abstract base class for a parametrized demographic model (a named set of populations, founder/migration events and parameters), together with the founder and migration event base classes it is built from, and FixedParametersHandler for fixing a subset of parameters by value or from observed ancestry proportions. Subclassed by ParametrizedDemography and ParametrizedDemographySexBiased.

Functions

smooth_clip01(x[, beta])	approaches 0 if x<0, 1 if x>1, approx linear in between
softplus(x[, beta])

Classes

BaseFounderEvent(found_time, ...[, ...])	Base class for founder events.
BaseMigrationEvent(rate_parameter, ...)	Base class for migration events.
BaseParametrizedDemography([name, min_time, ...])	Base class for parametrized demographies.
FixedParametersHandler(logger)	A class that handles the fixing of parameters based on ancestry proportions.
FounderEvent(found_time, source_populations, ...)	A class that sets up a founder event.
