In vecmatch: Generalized Propensity Score Estimation and Matching for Multiple Groups

Extract Parameter Grid for Selected Configurations

Description

Extract Parameter Grid for Selected Configurations

Usage

get_select_params(x, smd_group = NULL)

Arguments

x	A select_result object returned by select_opt().
smd_group	Optional character vector of SMD groups (e.g. "0.10-0.15"). If provided, the returned data.frame is subsetted to these groups. If NULL, all rows are returned.

Value

A data.frame with the parameter combinations corresponding to the selected configurations.

Examples

# Define formula and set up optimization
formula_cancer <- formula(status ~ age * sex)
opt_args <- make_opt_args(cancer, formula_cancer, gps_method = "m1")
withr::with_seed(8252, {
  opt_results <- optimize_gps(
    data = cancer,
    formula = formula_cancer,
    opt_args = opt_args,
    n_iter = 2000
  )
})
# Select optimal combinations prioritizing SMD balance and matching in key
# groups
select_results <- select_opt(
  x = opt_results,
  smd_groups = list(
    c("adenoma", "control"),
    c("control", "crc_benign"),
    c("crc_malignant", "control")
  ),
  smd_variables = "age",
  smd_type = "max",
  perc_matched = c("adenoma", "crc_malignant")
)

# Extract the parameter grid from select_results for smd_group = "0.05-0.10"
get_select_params(select_results, smd_group = "0.05-0.10")
