Allocate stations across strata
Description
Allocates stations across strata based on: stratum size, historical standard
deviation of cpue, ex vessel price, and abundance of a preselected subset of
species (reference a tech memo for how exactly Neyman allocations are handled?).
Created 12/18/13
Usage
allocate.effort(
channel = NULL,
species_weightings = NULL,
stratum_stats = NULL,
n_total = 400,
min_n_stratum = 2
)
Arguments
channel
open connection object. Created from gapindex::get_connected()
species_weightings
dataframe of species codes and weightings
stratum_stats
dataframe of stratum means and sds for each species
n_total
integer. Number of total stations
min_n_stratum
integer. Minimum number of stations in a stratum
Value
A named vector of allocated stations across strata
