poisson_distribution::poisson_distribution

 

Constructs the distribution.

Syntax

explicit poisson_distribution(RealType mean = 1.0);

explicit binomial_distribution(const param_type& parm);

Parameters

  • mean
    The mean distribution parameter.

  • parm
    The parameter structure used to construct the distribution.

Remarks

Precondition: 0.0 < mean

The first constructor constructs an object whose stored p value holds the value p.

The second constructor constructs an object whose stored parameters are initialized from parm. You can obtain and set the current parameters of an existing distribution by calling the param() member function.
