Sample size for a coefficient of variation
Description
Computes an approximate sample size required to estimate a population
coefficient of variation (CV) with desired confidence interval precision.
Set the CV planning value to the largest value within a plausible range
for a conservatively large sample size.
Usage
size.ci.cv(alpha, CV, w)
Arguments
alpha
alpha level for 1-alpha confidence
CV
planning value of coefficient of variation
w
desired confidence interval width
Value
Returns the required sample size
Examples
size.ci.cv(.05, .25, .10)
# Should return:
# Sample size
# 60
