Analytical Population Estimate Data

Description

Analytical estimates for a population

Abundance

Stratum: Stratum that abundance is provided for.
Domain: The domain that the abundance is provided for.
Abundance: The estimated number of individuals in the domain and stratum.
Frequency: The estimated fraction of individuals in the domain, relative ot the total number in stratum.

Variables

Stratum: The stratum that estimates are provided for.
Domain: The domain that estimates are provided for.
Variable: The variable (measurment) that estimates are provided for.
Total: The estimated total value of the variable in domain and stratum.
Mean: The estimated mean value fo the variable in domain and stratum.

AbundanceCovariance

Stratum: The stratum that covariances are provided for.
Domain1: A domain that covariances are provided for. Unique, given Stratum
Domain2: A domain that covariances are provided for. Unique, given Stratum and Domain 1.
AbundanceCovariance: The estimated covariance of abundance between Domain1 and Domain2.
FrequencyCovariance: The estimated covariance of frequency between Domain1 and Domain2.

VariableCovariance

Stratum: The stratum that covariances are provied for.
Domain1: A domain that covariances are provided for. Unique, given Stratum
Domain2: A domain that covariances are provided for. Unique, given Stratum and Domain 1.
Variable1: A variable that covariances are provided for. Unique, given Stratum and domains.
Variable2: A variable that covariances are provided for. Unique, given Stratum, domains and Variable1.
TotalCovariance: The estimated covariance of total value of Variable1 in Domain1 and Variable2 in Domain2
MeanCovariance: The estimated covariance of the mean value of Variable1 in Domain1 and Variable2 in Domain2

StratificationVariables

Stratum: A stratum, as identified in other tables.
<StratificationVariables>: Columns that relate the stratum to data records.

The columns <StratificationVariables> are optional, but if present; their combination must identify a stratum. The Stratification Variables assist in matching each strata to census data, such as landings. See for instance AnalyticalRatioEstimate Unlike PSUSamplingParametersData, AnalyticalPSUEstimateData, and, IndividualSamplingParametersData, a stratum for 'AnalyticalPopulationEstimateData' can be defined by several rows in the 'StratificationVariables' table.

DomainVariables

Domain: A domain, as identified in other tables.
DomainVariables: Columns that relate the domain to data records.

SampleCount

Stratum: A stratum, as identified in other tables.
Domain: A domain, as identified in other tables.
nPSU: The number of Primary Sampling Units observed for this domain in this stratum
nIndividuals: The number of individuals observed for this domain in this stratum
