About the author
Martin R. Bellford is the editorial pen name used for educational material on structured decision-making, cost comparison, uncertainty and tradeoff analysis.
The profile represents the research and editorial function behind the site, not a licensed financial adviser, accountant, lawyer, engineer or other regulated professional.
Editorial method
Guides begin with a defined decision pattern and explain when the model fits, what inputs it needs, how it works, what can go wrong and how to test the result. Examples use rounded, invented assumptions rather than market forecasts.
Corrections
Specific factual corrections can be submitted through the publisher help desk listed on the Contact page.
