In samplingR: Sampling and Estimation Methods

Strata allocation given a sample size

Description

Function to allocate the number of samples to be taken for each strata given the total sample size and the strata.allocation method. The number of allocations returned will be equal to the length of the parameters.

Usage

strata.allocation(
  Nh,
  n,
  var,
  alloc = c("unif", "prop", "min", "optim"),
  C,
  cini,
  ch
)

Arguments

Nh	Vector of population strata sizes.
n	Sample size
var	Vector of strata variances.
alloc	The allocation method to be used. Default is "unif".
C	Total study cost.
cini	Overhead study cost.
ch	Vector of costs to take an individual from a strata for the sample.

Details

alloc="optim" is the only that requires cost function data. Total study and overhead study costs are optional. If given allocation will be done so total study cost is not surpassed.s

Value

Vector of strata sample sizes.

Examples

strata.allocation(Nh=rep(125,4), n=100, alloc="unif") #25, 25, 25, 25
strata.allocation(Nh=c(100, 50, 25), n=100, alloc="prop")
