Optimize the Matching Process via Random Search

Source: R/optimize_gps.R
optimize_gps.Rd

The optimize_gps() function performs a random search to identify optimal combinations of parameters for the match_gps() and estimate_gps() functions. The goal is to maximize the percentage of matched samples (perc_matched) while minimizing the maximum standardized mean difference (smd), thereby improving the overall balance of covariates across treatment groups. The function supports parallel execution through the foreach and future packages, enabling multithreaded computation to accelerate the optimization process, particularly when dealing with large datasets or complex parameter spaces.

Usage

optimize_gps(
  data = NULL,
  formula,
  ordinal_treat = NULL,
  n_iter = 1000,
  opt_args = NULL
)

Arguments

data

A data.frame containing all variables specified in the formula argument. If opt_args is used, the data provided within opt_args must match this input exactly.

formula

A valid formula object used to estimate the generalized propensity scores (GPS). The treatment variable appears on the left-hand side, and covariates on the right-hand side. Interactions can be specified using *. See stats::formula() and estimate_gps() for more details. If opt_args is provided, the formula within it must be identical to this argument.

ordinal_treat

An atomic vector defining the ordered levels of the treatment variable. This confirms the variable is ordinal and adjusts its levels accordingly using factor(treat, levels = ordinal_treat, ordered = TRUE). It is passed directly to estimate_gps(). If NULL, ordinal GPS estimation methods such as polr will be excluded from the optimization. See estimate_gps() for details.

n_iter

Integer. Number of unique parameter combinations to evaluate during optimization. Higher values generally yield better results but increase computation time. For large datasets or high-dimensional parameter spaces, increasing n_iter is recommended. When using parallel processing (n_cores > 1), performance gains become more apparent with larger n_iter. Too many cores with too few iterations may introduce overhead and reduce efficiency.

opt_args

An object of class "opt_args" containing optimization parameters and argument settings. Use make_opt_args() to create this object. It specifies the search space for the GPS estimation and matching procedure.

Value

An S3 object of class best_opt_result. The core component is a data.frame containing the parameter combinations and results of the optimization procedure. You can access it using attr(result, "opt_results") or by calling View(result), where result is your best_opt_result object.

The object contains the following custom attributes:

  • opt_results: A data.frame of optimization results. Each row corresponds to a unique parameter combination tested. For a complete description of columns, see the Details section.

  • optimization_time: Time (in seconds) taken by the optimization loop (i.e., the core for-loop that evaluates combinations). This does not include the time needed for GPS estimation, pre-processing, or merging of results after loop completion. On large datasets, these excluded steps can still be substantial.

  • combinations_tested: Total number of unique parameter combinations evaluated during optimization.

  • smd_results: A detailed table of standardized mean differences (SMDs) for all pairwise treatment group comparisons and for all covariates specified in the formula. This is used by the select_opt() function to filter optimal models based on covariate-level balance across groups.

  • treat_names: A character vector with the names of the unique treatment groups.

  • model_covs: A character vector listing the model covariates (main effects and interactions) used in the formula. These names correspond to the variables shown in the smd_results table.

Details

The output is an S3 object of class best_opt_result. Its core component is a data.frame containing the parameter settings for the best-performing models, grouped and ranked based on their balance quality.

Optimization results are categorized into seven bins based on the maximum standardized mean difference (SMD):

  • 0.00-0.05

  • 0.05-0.10

  • 0.10-0.15

  • 0.15-0.20

  • 0.20-0.25

  • 0.25-0.30

  • Greater than 0.30

Within each SMD group, the parameter combination(s) achieving the highest perc_matched (i.e., percentage of matched samples) is selected. In cases where multiple combinations yield identical smd and perc_matched, all such results are retained. Combinations where matching failed or GPS estimation did not converge will return NA in the result columns (e.g., perc_matched, smd).

The returned data.frame includes the following columns (depending on the number of treatment levels):

  • iter_ID: Unique identifier for each parameter combination

  • method_match: Matching method used in match_gps(), e.g., "nnm" or "fullopt"

  • caliper: Caliper value used in match_gps()

  • order: Ordering of GPS scores prior to matching

  • kmeans_cluster: Number of k-means clusters used

  • replace: Whether replacement was used in matching (nnm only)

  • ties: Tie-breaking rule in nearest-neighbor matching (nnm only)

  • ratio: Control-to-treated ratio for nnm

  • min_controls, max_controls: Minimum and maximum controls for fullopt

  • reference: Reference group used in both estimate_gps() and match_gps()

  • perc_matched: Percentage of matched samples (from balqual())

  • smd: Maximum standardized mean difference (from balqual())

  • p_{group_name}: Percent matched per treatment group (based on group s ample size)

  • method_gps: GPS estimation method used (from estimate_gps())

  • link: Link function used in GPS model

  • smd_group: SMD range category for the row

The resulting best_opt_result object also includes a custom summary() method that summarizes:

  • The number of optimal parameter sets per SMD group

  • Their associated SMD and match rates

  • Total combinations tested

  • Total runtime of the optimization loop
