Business and financial plots#

Decile analysis becomes useful when statistical ranking is translated into an operational decision.

Response and cumulative response

Show where positive responses concentrate as more ranked cases are selected.

Lift and cumulative gain

Compare a model-guided selection with a random baseline.

Costs, revenue, profit, and ROI

Combine selection counts with explicit fixed costs, variable costs and per-unit profit assumptions.

Financial plots are scenario calculations, not accounting records. Keep units, currency, time horizon, treatment capacity, and cost assumptions alongside the figure. Highlighting a chosen ntile is useful only when the selection policy is actually constrained to that portion of the ranked population.
