Controlled Count Bounds for Balanced Sampling

bound() is a declarative marker used inside the aux argument of draw() with method = "cube". It requests adjacent-integer bounds on the realized sample count for every observed category of x.

Usage

bound(x)

Arguments

x

A single categorical frame variable. Use separate bound() calls for separate marginal constraints.

Value

bound() is only meaningful inside draw(aux = ...) and otherwise throws an informative error.

Examples

sampling_design() |>
  draw(
    n = 100,
    method = "cube",
    aux = c(income, bound(region), bound(urban_rural))
  )
