chi_squared_distribution() : chi_squared_distribution(1.0) {}
(1) (since C++11)
explicit chi_squared_distribution( RealType n );
(2) (since C++11)
explicit chi_squared_distribution( const param_type& params );
(3) (since C++11)

Constructs a new distribution object. (2) uses n as the distribution parameter. (3) uses params as the distribution parameter.

[edit] Parameters

n - the n distribution parameter (degrees of freedom)
params - the distribution parameter set
