ems:PoissonDistribution

Probability distributions: ems:PointEstimate, ems:UniformDistribution, ems:TriangularDistribution, ems:NormalDistribution, ems:PoissonDistribution, ems:QuantileFunction, ems:CumulativeDistributionFunction

Description

The Poisson distribution describes the number of independent, rarely occuring events that are observed in a given time interval. For example, defect arrivals or build failures could be estimated using this distribution.

An ems:PoissonDistribution resource represents a Poisson distribution.

Properties

An ems:PoissonDistribution has the following property:

Property Range Type Occurrence Edits Description
ems:lambda datatype xsd:double exactly-one read-write The expected number of occurences.

ems:lambda

This required property is the expected number of observations of the event, traditionally denoted by the Greek letter lambda.

Examples

Poisson Distribution 1

The following resource represents a Poisson distribution with a lambda value of 4:
