Remarks

The binomial distribution Binomial(n, probability) characterizes the probability of the number of successes in a variable of n trials, each having a probability probability of being successful.

If n = 1, the binomial distribution reduces to the BernoulliDistribution.

Example

The number of dice showing a six when rolling N dice has a biomial distribution with n = N and probability = 1/6. Notice that it doesn't matter if the trials are run simultaneously or in succession.

Constructors

BinomialDistribution(Int32) Constructs a new BinomialDistribution with the specified number of trials. The probability of success is set to 0.5.
BinomialDistribution(Vector<Double>) Estimates the parameters of the distribution of a variable assuming it follows a binomial distribution.
BinomialDistribution(Int32, Vector<Double>) Estimates the parameters of the distribution of a variable assuming it follows a binomial distribution.
BinomialDistribution(Int32, Double) Constructs a new BinomialDistribution with the specified number of trials and probability of success.
