Power analysis with specified distribution (aggregate mode)

Default power analysis method (aggregate mode with defaults)

Usage

# S3 method for class 'character'
power_analysis(
  distribution,
  params,
  effect_size = NULL,
  n_per_group = NULL,
  target_power = NULL,
  alpha = 0.05,
  test = "wilcoxon",
  find = "power",
  n_sim = 1000,
  ...
)

# Default S3 method
power_analysis(distribution, ...)

Arguments

distribution: Distribution name (e.g., "norm", "gamma", "lnorm")
params: List of distribution parameters
effect_size: Fold change to detect
n_per_group: Sample size per group (required for find="power")
target_power: Target power (required for find="sample_size" or find="effect_size")
alpha: Significance level (default 0.05)
test: Statistical test to use (default "wilcoxon")
find: What to solve for: "power", "sample_size", or "effect_size"
n_sim: Number of simulations (default 1000)
...: Additional arguments (ignored)

Value

A peppwr_power object
