In sdaza/sampler: Functions to Estimate Margins of Error (MOE) and Sample Sizes for a Proportion

Description

This function provides flexibility to estimate margins of errors for a proportion with a stratified sample assuming different population sizes, confidence levels, design effects (DEff), and response rates.

Usage

serrst(n, N = NULL, W = NULL, deff = 1, rr = 1, p = 0.5, cl = 0.95,
  relative = FALSE)

Arguments

n	Vector of sample size of each stratum.
N	Value or vector of values with the population size of each stratum.
W	Proportion of each stratum in the target population. If the population size is not specified, MOEs are estimated using the infinite population formula.
deff	A value or vector of values with design effects (DEff) provided from previous studies.
rr	Proportion representing expected response rate, it migth be 0 or more, and less than 1.
p	Value or vector of values with the expected proportion of each stratum.
cl	Confidence levels, e.g., .95
relative	Logical parameter. Estimate a relative error if TRUE.

Examples

serrst(n = c(100, 300, 100), N = c(500, 1000, 600))
