Get Total Catch Bounds by Landing Site and Gear

get_total_catch_bounds.Rd

Computes outlier bounds for total catch (total_catch_kg) grouped by the combination of landing_site and gear. Internally, it first aggregates catch_kg to get a single total_catch_kg per submission, then applies LocScaleB (with a log transform) within each site-gear group.

Usage

get_total_catch_bounds(data, k)

Arguments

data

A data frame containing submission_id, landing_site, gear, and catch_kg.

k

A numeric parameter passed to LocScaleB.

Value

A data frame with columns:

  • landing_site

  • gear

  • upper.up (the exponentiated upper bound)

Details

  1. Groups by submission_id, landing_site, gear and sums catch_kg into total_catch_kg.

  2. Splits the results by site-gear combination.

  3. Calls LocScaleB on each group, exponentiates the upper.up bound, then returns a data frame with landing_site, gear, and upper.up.

See also

validate_total_catch for usage of these bounds in validation.

Examples

if (FALSE) { # \dontrun{
total_bounds <- get_total_catch_bounds(data, k = 3)
head(total_bounds)
} # }
