class ContinuousEvent(start_parameter, end_parameter, rate_parameter, source_population)

Bases: BaseMigrationEvent

A class representing a continuous migration event, parametrized by start time, end time, and rate.

start_parameter

The name of the parameter defining the start time of the continuous migration.

Type:

str

end_parameter

The name of the parameter defining the end time of the continuous migration.

Type:

str

rate_parameter

The name of the parameter defining the rate of the continuous migration.

Type:

str

source_population

The name of the source population for the continuous migration.

Type:

str

__init__(start_parameter, end_parameter, rate_parameter, source_population)

Initializes a ContinuousEvent object.

Parameters:

• start_parameter (str) – The name of the parameter defining the start time of the continuous migration.

• end_parameter (str) – The name of the parameter defining the end time of the continuous migration.

• rate_parameter (str) – The name of the parameter defining the rate of the continuous migration.

• source_population (str) – The name of the source population for the continuous migration.

execute(parametrized_demography, migration_matrix, params)

Adds the continuous migration event to the migration matrix.

Parameters:

• parametrized_demography (ParametrizedDemography) – The parametrized demographic model.

• migration_matrix (ndarray) – The migration matrix to update.

• params (list[float]) – The list of parameter values.
