get_n_clusters: Calculate number of clusters to sample to reach target sample size

Description

Calculate number of clusters to sample to reach target sample size

Usage

get_n_clusters(n, n_cluster, u5, p)

Value

A numeric value of the estimated number of clusters to sample to reach target sample size.

Arguments

n

Target sample size of cases for the coverage survey.

n_cluster

Average cluster population for all ages in the specified survey area.

u5

Proportion (value from 0 to 1) of population that are aged 6-59 months.

p

Prevalence (value from 0 to 1) of condition that is to be assessed.

Examples

## Calculate number of villages to sample given an average village population
## of 600 persons of all ages with an under-5 population of 17% and a
## prevalence of SAM of 2% if the target sample size is 40
get_n_clusters(n = 40, n_cluster = 600, u5 = 0.17, p = 0.02)
