In validmeasures/sampsizer: An Implementation of Equations for Calculating Sample Sizes for Various Estimators in R

Description

Function to calculate design effect (DEFF) given intracluster correlation coefficient (ICC) and cluster size.

Usage

get_deff(x, cluster, size)

Arguments

x	variable to calculate ICC from
cluster	variable identifying the clusters or groupings of the variable
size	number of samples within a cluster

Value

A numeric value for design effect (DEFF)

Examples

  x <- sample(1:2, size = 25, replace = TRUE)
  cluster <- c(rep(1, 5), rep(2, 5), rep(3, 5), rep(4, 5), rep(5, 5))
  get_deff(x = x, cluster = cluster, size = 10)
