Calculate number of clusters to sample to reach target sample size
Usage
get_n_clusters(n, N, u5, p)
Arguments
- n
Target sample size of cases for the coverage survey
- N
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 of condition that is to be assessed
Value
Numeric value of the estimated number of clusters to sample to reach
target sample size
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 = 600, u5 = 0.17, p = 0.02)
