Forecasting, Business judgment

Insights 9

Evaluate against past decision-makers with a selective-labels method, not on approved cases alone
Flag capacity-constrained observations before treating sales as demand
Unconstrain sold-out flights before training a demand forecast
Separate stockout zeros from true zero demand before modelling a retail series
Use bookings already on hand as a known-at-origin input for departure-level forecasts
Model spill and unconstrained demand before estimating gains from added capacity
Evaluate a demand forecast against sales through the capacity cap, using quantiles
Do not measure bias on uncensored days only, because dropping stock-outs selects low-demand days
