Extracts a chi_squared_distribution random number distribution __x from the input stream __is.

class std::chi_squared_distribution< _RealType >“A chi_squared_distribution random number distribution.

The formula for the normal probability mass function is \(p(x|n) = ac{x^{(n/2) - 1}e^{-x/2}}{Gamma(n/2) 2^{n/2}}\)
