Statistics Final Year Topic: Poisson and Negative-Binomial Regression under Controlled Count Overdispersion

This Statistics final year project uses simulated counts with a stated mean structure and dispersion parameter to investigate a specific question in count-data modelling. 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 count overdispersion an explicit, reproducible comparison. Working with simulated counts with a stated mean structure and dispersion parameter lets you separate the target quantity from its estimate and explain when a statistical conclusion depends on assumptions.

How does extra-Poisson variation affect coefficient uncertainty and predictive fit in two count-regression models?

Agree the scenario ranges, sample sizes and reporting measures for count overdispersion before running the study.

Proposed project objectives

01Specify the data-generating conditions for simulated counts with a stated mean structure and dispersion parameter.
02Implement a reproducible analysis of count overdispersion with documented software settings.
03Evaluate the estimates and uncertainty relevant to this question: How does extra-Poisson variation affect coefficient uncertainty and predictive fit in two count-regression models?

A suggested research approach

Fit Poisson and negative-binomial models across a dispersion grid. Compare convergence, coefficient coverage and held-out count predictions, keeping offsets and exposure definitions consistent. 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 simulated counts with a stated mean structure and dispersion parameter
Statistical software supporting count-data modelling and reproducible scripts
A supervisor-agreed range of scenarios and computational budget

Keep your project scope clear

A negative-binomial model is one account of overdispersion and does not establish its real-world generating mechanism.
