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


A point estimate is simply an estimate that consists of a single value. It is a degenerate type of probability distribution since it is concentrated at a single point. In general, an estimate should include non-zero probabilities for some range of values. A point estimate can be used In the absence of any further information about the distribution of values, but estimators should improve their estimates by providing range information. Therefore, a point estimate may be used as a placeholder until a more realistic estimate is available.

An ems:PointEstimate resource represents a point estimate.


An ems:PointEstimate resource has the following property:

Property Range Type Occurrence Edits Description
ems:numericValue datatype xsd:double exactly-one read-write The estimated value.


This is the estimated value . The probability is one that a measurement will have this value and zero otherwise.


Point Estimate 1

The following resource represents a point estimate with a value of 6:
