Details |
The PROBNEGB function returns the probability that an observation from a negative binomial distribution, with probability of success p and number of successes n, is less than or equal to m.
To compute the probability that an observation is equal to a given value m, compute the difference of two probabilities from the negative binomial distribution for m and m-1.
