Attrition and influence after a verified design

Attrition and influence diagnostics can support sensitivity review, but they do not replace the verified external target or authorize outcome-driven reweighting.

After a weight plan is locked, inspect influential units without changing the weights:

influence <- wf_influence(
  locked,
  target = target,
  sample = design$data,
  id = design$roles$id,
  top = 20
)

influence$table

If panel-retention weights are studied, keep their formula, stabilization, trim settings, and balance diagnostics as a separate sensitivity analysis. Do not select those settings to make an outcome cross a preferred threshold.

impact <- wf_assess_impact(
  locked,
  analysis_data,
  id = "person_id",
  outcomes = c("score", "approved")
)

wf_report(impact, audience = "statistician")
