adjust_CVs

R Documentation

adjustCVs

Description

Function to increase or decrease the precision constraints in order to obtain the desired sample size

Usage

adjust_CVs(target_size, strata, errors, adj_rate = 0.01)

Arguments

`target_size`	desired sample size.
`strata`	the 'strata' dataset.
`errors`	the 'errors' dataset containing the current precision constraints
`adj_rate`	the rate of adjustment (default=0.01): the smaller, the higher the precision in reaching the target size; the higher, the quicker is the adjustment

Value

the new 'errors' dataset containing the modified precision constraints

Examples

data(beat.example)
errors
a <- beat.1st(strata,errors)
sum(a$alloc$ALLOC[-nrow(a$alloc)])
errors_new <- adjust_CVs(9000,strata,errors,adj_rate=0.005)
errors_new
