In FESta: Fishing Effort Standardization

#' SVstd_dataset
#'
#' A simulated fisheries dataset for demonstrating standard vessel
#' CPUE standardization methods.
#'
#' The dataset contains annual fishing observations for multiple vessels,
#' together with fishing effort and catch information. It is intended for
#' illustrating the application of the \code{SVstd()} function in the
#' FESta package.
#'
#' Catch values were generated so that the resulting catch per unit effort
#' values remain moderate, producing standardized CPUE indices close to
#' unity under the standard vessel approach.
#'
#' @format A data frame with 1000 observations and 4 variables:
#' \describe{
#'   \item{Year}{Fishing year.}
#'   \item{Vessel}{Fishing vessel identifier.}
#'   \item{Effort}{Fishing effort expended during the fishing operation.}
#'   \item{Catch}{Observed catch associated with the fishing effort.}
#' }
#'
#' @details
#' The dataset was generated to demonstrate standard vessel
#' standardization procedures. The catch values were adjusted so that
#' the resulting standardized CPUE values remain close to one,
#' facilitating interpretation of abundance indices produced by
#' \code{SVstd()}.
