Mastering Monte Carlo and Probabilistic Thinking
Match shapes to phenomena: lognormal for prices, triangular for expert estimates, beta for rates bounded between zero and one. Fit parameters from history and judgment, then validate with backtests so probability speaks credibly in boardrooms.
Mastering Monte Carlo and Probabilistic Thinking
Independent draws lie. Use correlation matrices or copulas to link demand, price, and cost shocks. Stress tails deliberately, because bad things rarely travel alone. Document assumptions so risk committees can reproduce and approve your methodology.
