Sweep Type I error rate across confounding strength levels

Usage

sweep_null_by_conf(
  conf_grid = c(0.2, 0.4, 0.6, 0.8, 1),
  n_iter = 100,
  n_samples = 500,
  n_features = 20,
  w_signal = 0.7,
  feat_cor = 0,
  base_seed = 900,
  n_cores = 1,
  alpha = 0.05
)

Arguments

conf_grid: Numeric vector of confounding strength values. Default c(0.2, 0.4, 0.6, 0.8, 1.0).
n_iter: Replicates per conf_str value. Default 100.
n_samples: Observations per replicate. Default 500.
n_features: Features per replicate. Default 20.
w_signal: Proxy quality omega. Default 0.70.
feat_cor: Within-module feature correlation. Default 0.
base_seed: Seed offset. Default 900.
n_cores: Parallel workers. Default 1.
alpha: Significance threshold. Default 0.05.

Value

A data frame with columns: conf_str, method, type1_error.

Examples

t1e <- sweep_null_by_conf(c(0.2, 0.8), n_iter = 3, n_samples = 100)
plot_type1_vs_conf(t1e)
