Takes a vector of weights, or data frame or list containing sets of weights, and resamples indices for use in later computation.
get_resampling_idxs(x, frac = 1, replace = TRUE)A vector of weights, a list of weight vectors, or a data frame of
type adjustr_weighted containing a .weights list-column
of weights.
A real number giving the fraction of draws to resample; the
default, 1, resamples all draws. Smaller values should be used when
replace=FALSE.
Whether sampling should be with replacement. When weights
are extreme it may make sense to use replace=FALSE, but accuracy
is not guaranteed in these cases.
A vector, list, or data frame, depending of the type of x,
containing the sampled indices. If any weights are NA, the indices
will also be NA.
