Generates a vector of random variates from a Negative Binomial distribution with probability \(f (X)\) defined by:
\[f (X) = \frac{(M + X - 1)! P^X(1-P)^M}{X!(M-1)!},X=0,1,\dotsi\]
C Generate 100 values from the Negative Binomial distribution
INTEGER LSTATE,N
PARAMETER (LSTATE=16,N=100)
INTEGER I,INFO,SEED(1),STATE(LSTATE)
INTEGER M
DOUBLE PRECISION P
INTEGER X(N)
C Set the seed
SEED(1) = 1234
C Read in the distributional parameters
READ(5,*) M,P
C Initialize the STATE vector
CALL DRANDINITIALIZE(1,1,SEED,1,STATE,LSTATE,INFO)
C Generate N variates from the Negative Binomial distribution
CALL DRANDNEGATIVEBINOMIAL(N,M,P,STATE,X,INFO)
C Print the results
WRITE(6,*) (X(I),I=1,N)
