Bases: BasicStructureRandomVariable

Describes a deterministic random variable

read_from_string(distribution_parameters)[source]#

Initialize distribution parameters from string

Parameters:

distribution_parameters – Current distribution parameters as exported on the Petri net

get_transition_type()[source]#

Get the type of transition associated to the current distribution

Returns:

String representing the type of the transition

get_value()[source]#

Get a random value following the distribution

Returns:

Value obtained following the distribution

Return type:

value

get_values(no_values=400)[source]#

Get some random values following the distribution

Parameters:

no_values – Number of values to return

Returns:

Values extracted according to the probability distribution
