Fisheries dependent Catch At Age Covariance Report (ReportFdaCatchAtAgeCovarianceData)

Covariances from catch at age estimations. Covariances are presented for age groups, together with any additional grouping (aggregation variables), such as gear, area, stock etc.

list with two members 'CovarianceNbyAge' and 'Variables'. 'CovarianceNbyAge' is a data.table which may have the following columns:

VariableId1

Identifies the one of the variables the covariance is calculated for

VariableId2

Identifies the other one of the variables the covariance is calculated for

Covariance

The covariance of catch at age in numbers between groups identified by 'Variable1' and 'Variable2'.

VariableId

Identifier for variable that covariances are provided for.

AgeGroup

character. The age group for the variable. May be age or plus group

Age

integer. The lower age group for the variable. May be an age or lower limit of plus group (inclusive)

...

Any aggregation variables.

Units are configurable, and can be inspected by ~getUnit
