sim_cbo {ecocbo}

Simulated cost-benefit optimization

Description

sim_cbo() can be used to apply a cost-benefit optimization model that depends either on a desired level of precision or on a budgeted total cost, as proposed by Underwood (1997).

Usage

sim_cbo(comp.var, multSE = NULL, ct = NULL, ck, cj)

Arguments

comp.var

Data frame as obtained from scompvar().

multSE

Optional. Required multivariate standard error for the sampling experiment.

ct

Optional. Total cost for the sampling experiment.

ck

Cost per replicate.

cj

Cost per unit.

Value

A data frame containing the optimized values for m number of sites and n number of samples to consider.
