Augment file B with synthetic records

Fits a generative model on encodedB[, PIVs] and draws n_synth new synthetic records from it, appended to encodedB with source = "synthetic"; used by compute_augmRL_FDP_synth() to estimate the false discovery proportion of a record-linkage method without ground truth.

Usage

synthesise(
  method,
  encodedA,
  encodedB,
  PIVs,
  n_synth,
  restrict_support_intersection = TRUE
)

Arguments

method

One of "arf" (arf::adversarial_rf()), "synthpop" (synthpop::syn()), or "mice" (mice::mice()).

encodedA

The (already prepared / encoded) data source.

encodedB

The (already prepared / encoded) data source.

PIVs

Character vector, names of the PIVs to synthesise.

n_synth

Integer, number of synthetic records to generate.

restrict_support_intersection

Logical; drop synthetic records whose PIV values fall outside the support shared with encodedA (default TRUE).

Value

List with dataA (unchanged encodedA, support-restricted) and dataB (encodedB plus the synthetic records).
