step_round: Round the final weights

In weightflow: Declarative API for Staged Survey Weights

Round the final weights

Description

Optional step, typically the last one (after calibration). Simple rounding ("nearest") slightly breaks the calibrated totals; "preserve_total" uses the largest-remainder method to keep the exact total.

Usage

step_round(spec, digits = 0L, method = c("nearest", "preserve_total"))

Arguments

spec	a weighting_spec.
digits	integer. Decimals to keep (0 = integers).
method	"nearest" (simple rounding) or "preserve_total" (keeps the sum of weights). Note: "preserve_total" can break equality of weights within a cluster; if you need integer and equal weights per household, use "nearest".

Value

The input weighting_spec with this step appended to its recipe. The step is recorded only; it is evaluated when prep() is called.

Examples

weighting_spec(sample_survey, base_weights = pw) |>
  step_round(digits = 0) |> prep()
