PET (Precision-Effect Test) Method

Implements the Precision-Effect Test for publication bias correction. PET regresses effect sizes against standard errors to test for and correct publication bias. The intercept represents the bias-corrected effect size estimate. See Stanley and Doucouliagos (2014) for details.

Usage

# S3 method for class 'PET'
method(method_name, data, settings = NULL)

Arguments

method_name

Method name (automatically passed)

data

Data frame with yi (effect sizes) and sei (standard errors)

settings

List of method settings (no settings version are implemented)

Value

Data frame with PET results

Examples

# Generate some example data
data <- data.frame(
  yi = c(0.2, 0.3, 0.1, 0.4, 0.25),
  sei = c(0.1, 0.15, 0.08, 0.12, 0.09)
)
