PROBBNML Function

Arguments

p

is a numeric probability of success parameter.

RANGE:

0 p 1

n

is an integer number of independent Bernoulli trials parameter.

RANGE:

n > 0

m

is an integer number of successes random variable.

RANGE:

0 m n

The PROBBNML function returns the probability that an observation from a binomial distribution, with probability of success p, number of trials n, and number of successes m, 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 binomial distribution for m and m-1 successes.
