Statistics Final Year Topic: Coverage of HC3 and Conventional Regression Intervals under Heteroskedasticity

This Statistics final year project uses linear-model simulations with known coefficients and controlled error variances to investigate a specific question in regression inference. The analysis is designed around known generating conditions so that the behaviour of competing statistical procedures can be checked.

Why choose this project topic?

This study makes robust standard errors an explicit, reproducible comparison. Working with linear-model simulations with known coefficients and controlled error variances lets you separate the target quantity from its estimate and explain when a statistical conclusion depends on assumptions.

How do HC3 and conventional standard errors affect coefficient-interval coverage under different variance patterns?

Agree the scenario ranges, sample sizes and reporting measures for robust standard errors before running the study.

Proposed project objectives

01Specify the data-generating conditions for linear-model simulations with known coefficients and controlled error variances.
02Implement a reproducible analysis of robust standard errors with documented software settings.
03Evaluate the estimates and uncertainty relevant to this question: How do HC3 and conventional standard errors affect coefficient-interval coverage under different variance patterns?

A suggested research approach

Keep the mean model correctly specified while varying the variance function and sample size. Compare coverage, average interval width and finite-sample instability using the same simulated datasets. Write the analysis before inspecting favourable runs, record random seeds where simulation is used, and keep generated study data distinct from observed field data.

What you will need

A written design for linear-model simulations with known coefficients and controlled error variances
Statistical software supporting regression inference and reproducible scripts
A supervisor-agreed range of scenarios and computational budget

Keep your project scope clear

Robust standard errors do not correct omitted-variable bias, dependence or an incorrectly specified conditional mean.
