---+ ems:PointEstimate Probability distributions: [[MetricsEmsPointEstimate][ems:PointEstimate]], [[MetricsEmsUniformDistribution][ems:UniformDistribution]], [[MetricsEmsTriangularDistribution][ems:TriangularDistribution]], [[MetricsEmsNormalDistribution][ems:NormalDistribution]], [[MetricsEmsPoissonDistribution][ems:PoissonDistribution]], [[MetricsEmsQuantileFunction][ems:QuantileFunction]], [[MetricsEmsCumulativeDistributionFunction][ems:CumulativeDistributionFunction]] %TOC% ---++ Description 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. ---++ Properties 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. | ---+++ ems:numericValue This is the estimated value . The probability is one that a measurement will have this value and zero otherwise. ---++ Examples ---+++ Point Estimate 1 The following resource represents a point estimate with a value of 6: ---++++++ Listing of Point Estimate 1 <blockquote><verbatim><?xml version="1.0"?> <ems:PointEstimate xmlns:ems="http://open-services.net/ns/ems#" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <ems:numericValue rdf:datatype="http://www.w3.org/2001/XMLSchema#double">6</ems:numericValue> </ems:PointEstimate> </verbatim></blockquote> ---++ Comments Enter your comments here: %COMMENT%
