Language: Fortran	Revised:

Subroutine subprogram RNBNML generates a random integer N>0 according to the binomial distribution

where the 'sample size' M>0 and the probability P ( ) are specified by the user.

Structure:

SUBROUTINE subprogram
User Entry Names: RNBNML
External References: RANLUX

Usage:

    CALL RNBNML(M,P,N,IERR)

M

(INTEGER) Sample size M.

P

(REAL) Probability P.

N

(INTEGER) The generated random number N, binomially distributed in the interval with mean .

IERR

(INTEGER) Error flag.
Normal case,
or .

Notes:

RNBNML should not be used when M is 'large' (say >100 ). The normal approximation is then recommended instead (with mean and standard deviation ).
