Provides statistical distributions.

Modifier and Type  Class and Description 

class 
BernoulliDistribution
A Bernoulli distribution, which takes a value of "1" with probability "p"
and value of "0" with probability "1p".

static class 
BernoulliDistribution.CDF
CDF of a Bernoulli distribution.

static class 
BernoulliDistribution.PMF
PMF of the Bernoulli distribution.

class 
BetaBinomialDistribution
A Binomial distribution where the binomial parameter, p, is set according
to a Beta distribution instead of a single value.

static class 
BetaBinomialDistribution.CDF
CDF of BetaBinomialDistribution

static class 
BetaBinomialDistribution.PMF
PMF of the BetaBinomialDistribution

class 
BinomialDistribution
Binomial distribution, which is a collection of Bernoulli trials

static class 
BinomialDistribution.CDF
CDF of the Binomial distribution, which is the probability of getting
up to "x" successes in "N" trials with a Bernoulli probability of "p"

static class 
BinomialDistribution.PMF
The Probability Mass Function of a binomial distribution.

class 
GeometricDistribution
The geometric distribution models the number of successes before the first
failure occurs under an independent succession of Bernoulli tests.

static class 
GeometricDistribution.CDF
CDF of the Geometric distribution

static class 
GeometricDistribution.PMF
PMF of the Geometric distribution

class 
NegativeBinomialDistribution
Negative binomial distribution, also known as the Polya distribution,
gives the number of successes of a series of Bernoulli trials before
recording a given number of failures.

static class 
NegativeBinomialDistribution.CDF
CDF of the NegativeBinomialDistribution

static class 
NegativeBinomialDistribution.PMF
PMF of the NegativeBinomialDistribution.

class 
PoissonDistribution
A Poisson distribution is the limits of what happens when a Bernoulli trial
with "rare" events are sampled on a continuous basis and then binned into
discrete time intervals.

static class 
PoissonDistribution.CDF
CDF of the PoissonDistribution

static class 
PoissonDistribution.PMF
PMF of the PoissonDistribution.

class 
UniformIntegerDistribution
Contains the (very simple) definition of a continuous Uniform distribution,
parameterized between the minimum and maximum bounds.

static class 
UniformIntegerDistribution.CDF
Implements the cumulative distribution function for the discrete
uniform distribution.

static class 
UniformIntegerDistribution.PMF
Probability mass function of a discrete uniform distribution.

class 
YuleSimonDistribution
The YuleSimon distribution is a model of preferential attachment, such as
a model of the number of groups follows a powerlaw distribution
(Zipf's Law).

static class 
YuleSimonDistribution.CDF
CDF of the YuleSimon Distribution

static class 
YuleSimonDistribution.PMF
PMF of the YuleSimon Distribution
