ssize: Estimation of sample sizes for a proportion

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 of a proportion assuming different population sizes, confidence levels, design effects (DEff), and response rates.

Usage

ssize(e, deff = 1, rr = 1, N = NULL, cl = 0.95, p = 0.5)

Arguments

e	Expected margin of error.
deff	Design effect (DEff). Generally, from studies and estimations. Values should be higher than 0.
rr	Proportion representing expected response rate, it migth higher than 0 and lower than 1.
N	Population size. If the population size is not specified, MOEs are estimated using an infinite population formula.
cl	Confidence levels, e.g., .95
p	Value or vector of values with the expected proportion.

Examples

ssize(e = 0.02, deff = 1.5, rr = .8, N = 1000)
ssize(e = 0.05)
