Compute standard error estimates based on the estimated influence function for a SPVIM value of interest.
spvim_se(ics, idx = 1, gamma = 1, na_rm = FALSE)
The standard error estimate for the desired SPVIM value
the influence function estimates based on the contributions
from sampling observations and sampling subsets: a list of length two
resulting from a call to spvim_ics
.
the index of interest
the proportion of the sample size used when sampling subsets

s?
Since the processes for sampling observations and subsets are independent, the variance for a given SPVIM estimator is simply the sum of the variances based on sampling observations and on sampling subsets.
