SamplingStrata (version 1.5-4)

expected_CV: Expected coefficients of variation of target variables Y

Description

Once optimized the sampling frame, this function allows to calculate the expected coefficients of variation on the aggregated strata of the current optimized solution, and to compare them to the precision constraints.

Usage

expected_CV(strata)

Value

Matrix containing values of the CV's in the different domains

Arguments

strata

Aggregated strata in the solution obtained by the execution of the 'optimizedStrata' function

Examples

if (FALSE) {
library(SamplingStrata)
data(swisserrors)
data(swissstrata)
# optimisation of sampling strata
solution <- optimizeStrata ( 
    errors = swisserrors, 
    strata = swissstrata, 
)
# calculate CV's on Y's
expected_CV(solution$aggr_strata)
# compare to precision constraints
swisserrors
}
