Validate diagnostics against reference implementations

Compares the package's test results with established implementations from other packages (currently lmtest and car). Differences exceeding the supplied tolerance are flagged.

Usage

rvalidate_against_reference(test_name, model, data, tolerance = 1e-06)

Arguments

test_name

Character scalar naming the diagnostic: "breusch_pagan", "studentized_bp", or "white".

model

A fitted stats::lm object representing the mean specification to be diagnosed.

data

A base::data.frame (or object coercible to one) containing the variables referenced by model. It must include the observations used to fit model and will be checked for missing values.

tolerance

Acceptable absolute difference between statistics and p-values when comparing to the reference implementation.

Value

A list describing the comparison, including a status field with values "ok", "mismatch", or "skipped" when the reference package is unavailable.
