A fisher_f_distribution random number distribution.

The formula for the normal probability mass function is p(x|m,n) = ac{Gamma((m+n)/2)}{Gamma(m/2)Gamma(n/2)} (ac{m}{n})^{m/2} x^{(m/2)-1} (1 + ac{mx}{n})^{-(m+n)/2} ]

Inserts a fisher_f_distribution random number distribution __x into the output stream __os.

Parameters:

__os An output stream.
__x A fisher_f_distribution random number distribution.

Returns:

The output stream with the state of __x inserted or in an error state.

Return true if two Fisher f distributions have the same parameters and the sequences that would be generated are equal.

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

Parameters:

__is An input stream.
__x A fisher_f_distribution random number generator engine.

Returns:

The input stream with __x extracted or in an error state.
