Estimator Standard Deviation at a Given Trial Size

Converts a fs_dgm_scale object into the sampling standard deviation of the within-region difference-in-means estimator at trial size n.

Usage

fs_scale_se(scale, n, region = NULL, jensen = FALSE)

scale: An object of class "fs_dgm_scale".
n: Integer. Trial size.
region: Character. Region name, matching a row of scale$regions. Default NULL returns every region.
jensen: Logical. If TRUE, inflate by the exact factor accounting for the random region size $n_g \sim \mathrm{Bin}(n, P(g))$ and random arm split $n_1 \mid n_g \sim \mathrm{Bin}(n_g, p)$, returning the unconditional standard deviation. Default FALSE, which returns the idealised (fixed-count) value.

Named numeric vector of standard deviations.
