The Fisher F distribution is a real valued distribution with two parameters m and n.
It has .
fisher_f_distribution
public
construct/copy/destruct( m = , n = );
Constructs a
from its "m" and "n" parameters.fisher_f_distribution
Requires: m > 0 and n > 0
(param_type & param);
Constructs an

fisher_f_distribution
public member functionstemplate<typename URNG> ( urng);
Returns a random variate distributed according to the F distribution.
template<typename URNG> ( urng, param_type & param) ;
Returns a random variate distributed according to the F distribution with parameters specified by param
.
() ;
Returns the "m" parameter of the distribution.
() ;
Returns the "n" parameter of the distribution.
() ;
Returns the smallest value that the distribution can produce.
() ;
Returns the largest value that the distribution can produce.
param_type () ;
Returns the parameters of the distribution.
(param_type & param);
Sets the parameters of the distribution.
();
Effects: Subsequent uses of the distribution do not depend on values produced by any engine prior to invoking reset.
