If we are tossing a coin, then the negative binomial distribution can give the number of tails "failures" we are likely to encounter before we encounter a certain number of heads "successes".

The probability mass function of the negative binomial distribution is. Here the quantity in parentheses is the binomial coefficient , and is equal to.

This quantity can alternatively be written in the following manner, explaining the name "negative binomial":. The cumulative distribution function can be expressed in terms of the regularized incomplete beta function :.

It can also be expressed in terms of the cumulative distribution function of the binomial distribution [5] :. Some sources may define the negative binomial distribution slightly differently from the primary one here.

The most common variations are where the random variable X is counting different things. These variations can be seen in the table here:. Each of these definitions of the negative binomial distribution can be expressed in slightly different but equivalent ways.

These second formulations may be more intuitive to understand, however they are perhaps less practical as they have more terms. Decrease of the aggregation parameter r towards zero corresponds to increasing aggregation of the organisms; increase of r towards infinity corresponds to absence of aggregation, as can be described by Poisson regression.

Pat Collis is required to sell candy bars to raise money for the 6th grade field trip. There are thirty houses in the neighborhood, and Pat is not supposed to return home until five candy bars have been sold.

So the child goes door to door, selling candy bars. At each house, there is a 0. Successfully selling candy enough times is what defines our stopping criterion as opposed to failing to sell it , so k in this case represents the number of failures and r represents the number of successes.

Selling five candy bars means getting five successes. The number of trials i. To finish on or before the eighth house, Pat must finish at the fifth, sixth, seventh, or eighth house.

Sum those probabilities:. This can be expressed as the probability that Pat does not finish on the fifth through the thirtieth house:.

Because of the rather high probability that Pat will sell to each house 60 percent , the probability of her NOT fulfilling her quest is vanishingly slim.

Hospital length of stay is an example of real-world data that can be modelled well with a negative binomial distribution.

To see this, imagine an experiment simulating the negative binomial is performed many times. That is, a set of trials is performed until r failures are obtained, then another set of trials, and then another etc.

Now we would expect about Np successes in total. Say the experiment was performed n times. Then there are nr failures in total.

That is what we mean by "expectation". This agrees with the mean given in the box on the right-hand side of this page. Suppose Y is a random variable with a binomial distribution with parameters n and p.

Using Newton's binomial theorem , this can equally be written as:. In this case, the binomial coefficient. We can then say, for example.

If r is a negative non-integer, so that the exponent is a positive non-integer, then some of the terms in the sum above are negative, so we do not have a probability distribution on the set of all nonnegative integers.

Now we also allow non-integer values of r. Then we have a proper negative binomial distribution, which is a generalization of the Pascal distribution, which coincides with the Pascal distribution when r happens to be a positive integer.

This property persists when the definition is thus generalized, and affords a quick way to see that the negative binomial distribution is infinitely divisible.

The following recurrence relation holds:. Consider a sequence of negative binomial random variables where the stopping parameter r goes to infinity, whereas the probability of success in each trial, p , goes to zero in such a way as to keep the mean of the distribution constant.

In other words, the alternatively parameterized negative binomial distribution converges to the Poisson distribution and r controls the deviation from the Poisson.

This makes the negative binomial distribution suitable as a robust alternative to the Poisson, which approaches the Poisson for large r , but which has larger variance than the Poisson for small r.

The binomial distribution is the PMF of k successes given n independent events each with a probability p of success.

Beta distributions also provide a family of prior probability distributions for binomial distributions in Bayesian inference : [26]. Given a uniform prior, the posterior distribution for the probability of success p given n independent events with k observed successes is a beta distribution.

Methods for random number generation where the marginal distribution is a binomial distribution are well-established.

One way to generate random samples from a binomial distribution is to use an inversion algorithm. These probabilities should sum to a value close to one, in order to encompass the entire sample space.

Then by using a pseudorandom number generator to generate samples uniformly between 0 and 1, one can transform the calculated samples into discrete numbers by using the probabilities calculated in the first step.

This distribution was derived by Jacob Bernoulli. From Wikipedia, the free encyclopedia. Probability distribution. For the binomial model in options pricing, see Binomial options pricing model.

Now we also allow non-integer values of r. Then we have a proper negative binomial distribution, which is a generalization of the Pascal distribution, which coincides with the Pascal distribution when r happens to be a positive integer.

This property persists when the definition is thus generalized, and affords a quick way to see that the negative binomial distribution is infinitely divisible.

The following recurrence relation holds:. Consider a sequence of negative binomial random variables where the stopping parameter r goes to infinity, whereas the probability of success in each trial, p , goes to zero in such a way as to keep the mean of the distribution constant.

In other words, the alternatively parameterized negative binomial distribution converges to the Poisson distribution and r controls the deviation from the Poisson.

This makes the negative binomial distribution suitable as a robust alternative to the Poisson, which approaches the Poisson for large r , but which has larger variance than the Poisson for small r.

The negative binomial distribution also arises as a continuous mixture of Poisson distributions i. Together, the Success and Failure processes are equivalent to a single Poisson process of intensity 1, where an occurrence of the process is a success if a corresponding independent coin toss comes up heads with probability p ; otherwise, it is a failure.

If r is a counting number, the coin tosses show that the count of successes before the r th failure follows a negative binomial distribution with parameters r and p.

The count is also, however, the count of the Success Poisson process at the random time T of the r th occurrence in the Failure Poisson process.

The following formal derivation which does not depend on r being a counting number confirms the intuition. Because of this, the negative binomial distribution is also known as the gamma—Poisson mixture distribution.

Note: The negative binomial distribution was originally derived as a limiting case of the gamma-Poisson distribution. The negative binomial distribution is infinitely divisible , i.

Then the random sum. To prove this, we calculate the probability generating function G X of X , which is the composition of the probability generating functions G N and G Y 1.

The following table describes four distributions related to the number of successes in a sequence of draws:. The negative binomial along with the Poisson and binomial distributions is a member of the a,b,0 class of distributions.

All three of these distributions are special cases of the Panjer distribution. They are also members of the Natural exponential family.

Suppose p is unknown and an experiment is conducted where it is decided ahead of time that sampling will continue until r successes are found.

A sufficient statistic for the experiment is k , the number of failures. In estimating p , the minimum variance unbiased estimator is. The maximum likelihood estimate of p is.

The maximum likelihood estimator only exists for samples for which the sample variance is larger than the sample mean.

To find the maximum we take the partial derivatives with respect to r and p and set them equal to zero:. This equation cannot be solved for r in closed form.

If a numerical solution is desired, an iterative technique such as Newton's method can be used. Alternatively, the expectation—maximization algorithm can be used.

For the special case where r is an integer, the negative binomial distribution is known as the Pascal distribution. It is the probability distribution of a certain number of failures and successes in a series of independent and identically distributed Bernoulli trials.

In other words, the negative binomial distribution is the probability distribution of the number of successes before the r th failure in a Bernoulli process , with probability p of successes on each trial.

A Bernoulli process is a discrete time process, and so the number of trials, failures, and successes are integers.

Consider the following example. Suppose we repeatedly throw a die, and consider a 1 to be a "failure". That number of successes is a negative-binomially distributed random variable.

The negative binomial distribution, especially in its alternative parameterization described above, can be used as an alternative to the Poisson distribution.

It is especially useful for discrete data over an unbounded positive range whose sample variance exceeds the sample mean. In such cases, the observations are overdispersed with respect to a Poisson distribution, for which the mean is equal to the variance.

Hence a Poisson distribution is not an appropriate model. Since the negative binomial distribution has one more parameter than the Poisson, the second parameter can be used to adjust the variance independently of the mean.

See Cumulants of some discrete probability distributions. An application of this is to annual counts of tropical cyclones in the North Atlantic or to monthly to 6-monthly counts of wintertime extratropical cyclones over Europe, for which the variance is greater than the mean.

The negative binomial distribution is also commonly used to model data in the form of discrete sequence read counts from high-throughput RNA and DNA sequencing experiments.

This distribution was first studied in , by Montmort, as the distribution of the number of trials required in an experiment to obtain a given number of successes.
