In tidysynthesis: A Common API for Synthesizing Data

Sample the conditional distribution created by a CART model

Description

Sample the conditional distribution created by a CART model

Usage

sample_rpart(model, new_data, conf_data, ignore_zeros = TRUE)

Arguments

model	A "model_fit" object created by rpart
new_data	A data frame with predictors
conf_data	A data frame with original confidential predictors
ignore_zeros	Should a vector of all 0 observations return NA for the l-diversity calculation. Defaults to TRUE.

Value

A numeric vector of predictions

Examples

rpart_mod_reg <- parsnip::decision_tree() |>
  parsnip::set_engine("rpart") |>
  parsnip::set_mode(mode = "regression")

 regression_rec <- recipes::recipe(inctot ~ ., data = acs_conf)
 
 model_reg <- workflows::workflow() |>
   workflows::add_model(spec = rpart_mod_reg) |>
   workflows::add_recipe(recipe = regression_rec) |>
   parsnip::fit(data = acs_conf)
 
 set.seed(1)
 sample1 <- sample_rpart(
