is the seed value. A new value for seed is returned each time CALL RANBIN is executed.
Range | seed < 2^{31} - 1 |
Note | If seed ≤ 0, the time of day is used to initialize the seed stream. |

is an integer number of independent Bernoulli trials.
Range | n > 0 |
is a numeric probability of success parameter.
Range | 0<p<1 |
is a numeric SAS variable. A new value for the random variate x is returned each time CALL RANBIN is executed.
