The mkl::rng::chi_square class object is used in the mkl::rng::generate function to provide random numbers with chi-square distribution and ν degrees of freedom, n ∈N, n > 0.
The probability density function is:
The cumulative distribution function is:
typename RealType = float |
Type of the produced values. The specific values are as follows: float double |
typename Method = mkl::rng::chi_square_method::by_default |
Generation method. The specific values are as follows: mkl::rng::chi_square_method::gamma_based See brief descriptions of the methods in Distributions Template Parameter Method Values |
