This negative binomial calculator can help you calculate the negative probability based on the number of trials (n), number of successes (x) and probability of success on a single trial (p).
What is a negative binomial experiment?
In statistics, a negative binomial experiment is an experiment having the following particularities:
■ The experiment is made of x repeated trials, while each trial can be considered either a success or a failure.
■ On every trial, the probability of success is constant, while the trials are independent as the outcome on a trial does not have any impact on the other trials success or failure.
■ Finally, a negative binomial experiment ends only when a specific number of successes established in advance is achieved.
How does this negative binomial calculator work?
The algorithm behind this negative binomial calculator uses the following formula:
NB(n; x, P) = n-1Cx-1 * Px * (1 - P)n – x
p = Probability of success on a single trial
n = Number of trials
x = Number of successes28 Jul, 2015 | 0 comments
