Performance Comparison Guide

Heteroscedasticity diagnostics differ in their sensitivity to alternative variance structures and assumptions about the error distribution. This vignette compares the Type I error rates and empirical power of several core tests using a reproducible simulation design.

Simulation design

We simulate data from a two-regressor linear model \[ y_i = 1 + 2 x_{i1} + 3 x_{i2} + \varepsilon_i, \] with covariates drawn from \(x_{i1} \sim \mathcal{N}(0,1)\) and \(x_{i2} = 0.5 x_{i1} + u_i\), \(u_i \sim \mathcal{N}(0,1)\). The error variance is controlled by the scenario:

Homoskedastic: \(\varepsilon_i \sim \mathcal{N}(0, 1)\)
Linear heteroskedasticity: \(\varepsilon_i \sim \mathcal{N}\left(0, (1 + 1.5 |x_{i1}|)^2\right)\)
Clustered heteroskedasticity: with probability 0.5 the observation enters a high-variance regime \(\mathcal{N}(0, 2.5^2)\), otherwise it remains at \(\mathcal{N}(0, 1^2)\)

generate_sample <- function(n = 180, scenario = c("homoskedastic", "linear", "clustered")) {
  scenario <- match.arg(scenario)
  x1 <- rnorm(n)
  x2 <- 0.5 * x1 + rnorm(n)
  if (scenario == "homoskedastic") {
    errors <- rnorm(n, sd = 1)
  } else if (scenario == "linear") {
    errors <- rnorm(n, sd = 1 + 1.5 * abs(x1))
  } else {
    regime <- rbinom(n, 1, 0.5)
    sds <- ifelse(regime == 1, 2.5, 1)
    errors <- rnorm(n, sd = sds)
  }
  y <- 1 + 2 * x1 + 3 * x2 + errors
  data.frame(y = y, x1 = x1, x2 = x2)
}

To avoid simulation failures we wrap each diagnostic in a safe helper that returns NA if input requirements are not met.

safe_pvalue <- function(fn) {
  res <- tryCatch(fn(), error = function(e) NULL)
  if (is.null(res) || is.null(res$p.value)) {
    NA_real_
  } else {
    res$p.value
  }
}

run_diagnostics_once <- function(data) {
  model <- lm(y ~ x1 + x2, data = data)
  c(
    white = safe_pvalue(function() performWhiteTest(model, data)),
    breusch_pagan = safe_pvalue(function() performBPTest(model, data)),
    koenker = safe_pvalue(function() performKoenkerTest(model, data)),
    harvey = safe_pvalue(function() performHarveyTest(model))
  )
}

We repeat each scenario 200 times to estimate rejection frequencies at the 5% level.

run_simulation <- function(scenario, reps = 200) {
  replicate(reps, run_diagnostics_once(generate_sample(scenario = scenario)), simplify = "matrix")
}

calc_rejection_rate <- function(result_matrix, alpha = 0.05) {
  rowMeans(result_matrix < alpha, na.rm = TRUE)
}

Interpretation. Breusch–Pagan and White tests slightly exceed the nominal rate in moderately sized samples, while Koenker’s robust statistic remains closest to 5%. Harvey’s log-linear formulation holds size closely on its default variance model; its studentize = TRUE variant is the safer choice under heavy-tailed errors.

Power against structured alternatives

We evaluate power under the linear and clustered variance patterns.

Interpretation. White’s omnibus test excels when heteroskedasticity follows a nonlinear pattern with multiple interaction terms (clustered scenario), whereas Breusch–Pagan is most powerful for smooth linear variance inflation. Koenker’s studentised variant sacrifices some power for robustness. Harvey’s log-linear regression on the model regressors performs strongly when the variance tracks those regressors, which occurs here because x1 dominates the signal.
