Select Optimal Parameter Combinations from Optimization Results

Source: R/optimize_gps.R
select_opt.Rd

select_opt() is a helper function to filter and prioritize results from optimize_gps() based on the specific goals of a study. Depending on the research design, certain pairwise comparisons or treatment groups may be more important than others. For example:

  • You may want to prioritize matching between a specific groups (e.g. specific disease vs. controls), while ignoring other group comparisons during SMD evaluation.

  • You may wish to retain as many samples as possible from a critical group or set of groups, regardless of matching rates in other groups.

This function enables targeted selection of optimal parameter combinations by:

  • Evaluating SMDs for specific pairwise treatment group comparisons,

  • Selecting key covariates to assess balance,

  • Prioritizing matched sample size in selected treatment groups.

By combining these criteria, select_opt() allows you to tailor the optimization output to your study's focus - whether it emphasizes covariate balance in targeted group comparisons or maximizing sample retention for specific subgroups.

Usage

select_opt(
  x,
  smd_groups = NULL,
  smd_variables = NULL,
  smd_type = c("mean", "max"),
  perc_matched = NULL
)

Arguments

x

An object of class best_opt_result, produced by the optimize_gps() function.

smd_groups

A list of pairwise comparisons (as character vectors of length 2) specifying which treatment group comparisons should be prioritized in SMD evaluation. Each element must be a valid pair of treatment levels. If NULL, all pairwise comparisons are used. Example: list(c("adenoma", "crc_malignant"), c("controls", "adenoma"))

smd_variables

A character vector of covariate names to include in the SMD evaluation. Must match variables listed in attr(x, "model_covs").

smd_type

A character string ("mean" or "max"), defining how to aggregate SMDs across covariates and comparisons. "max" selects combinations with the lowest maximum SMD; "mean" uses the average SMD.

perc_matched

A character vector of treatment levels for which the matching rate should be maximized. If NULL, overall perc_matched is used. If specified, only the sum of matching percentages for the listed groups is used for selection within each SMD category.

Value

An S3 object of class select_result, containing the filtered and prioritized optimization results. The object includes:

  • A data.frame with selected parameter combinations and performance metrics.

  • Attribute param_df: A data.frame with full parameter specifications (iter_ID, GPS/matching parameters, etc.), useful for manually refitting or reproducing results.

The object also includes a custom print() method that summarizes:

  • Number of selected combinations per SMD bin

  • Corresponding aggregated SMD (mean or max)

  • Overall or group-specific percentage matched

Details

Optimization results are grouped into bins based on the maximum SMD observed for each parameter combination. These bins follow the same structure as in optimize_gps():

  • 0.00-0.05

  • 0.05-0.10

  • 0.10-0.15

  • 0.15-0.20

  • 0.20-0.25

  • 0.25-0.30

  • 0.30-0.35

  • 0.35-0.40

  • 0.40-0.45

  • 0.45-0.50

  • more than 0.50

Within each bin, models are first filtered based on their aggregated SMD across the specified smd_groups and smd_variables, using the method defined by smd_type. Then, among the remaining models, the best-performing one(s) are selected based on the percentage of matched samples - either overall or in the specified treatment groups (perc_matched).
