Statistical properties (dyad.stats)

This module contains probability distributions for the masses and orbital elements of a population of binary stars.

Probability distributions

Each univariate distribution is an instance of a subclass of Scipy’s scipy.stats.rv_continuous class in the same way that univariate distributions in Scipy are.

longitude_of_ascending_node

The random variable for the longitude of the ascending node

inclination

The random variabe for inclination

argument_of_pericentre

The random variabe for the argument of pericentre

true_anomaly

The random variable for true anomaly

Submodules

Where there is a choice of distribution the options are made available in a submodule. For the distributions provided by a particular submodule see that module’s documentation. Conditional random variables are implemented using shape parameters to specify the value of the condition.

eccentricity

Eccentricity (dyad.stats.eccentricity)

log_period

Log-period (dyad.stats.log_period)

mass

Mass (dyad.stats.mass)

mass_ratio

Mass ratio (dyad.stats.mass_ratio)

semimajor_axis

Semimajor-axis (dyad.stats.semimajor_axis)

Warnings/errors used in dyad.stats

Dyad inherits the warnings and errors used in scipy.stats.
