Description
Given a Dirichlet distribution whose parameter vector α sums to
n_total, calc_var_dirichlet calculates the sampling variance
of an element i for which α_i = prop * n_total,
using the formula (prop * (1 - prop)) / (n_total + 1).
Usage
1
calc_var_dirichlet(prop, n_total)
Arguments
prop
stipulated proportion
n_total
the “sample size” of the Dirichlet distribution, i.e.,
∑ α_i.
Value
The sampling variance of the proportion
Examples
1
2
## standard error of a proportion of 0.5 given a sample size of 2,499
sqrt(calc_var_dirichlet(0.5, 2499))
