The Science Behind TSF
Traditional forecasting models operate on a single timeline — each day’s value depends on the one before it. That means when reality shifts mid-month, their forecasts can’t keep up; the curve is already locked into yesterday’s assumptions.
The Model of Temporal Inertia (MTI) changes this. TSF forecasts operate on two timelines at once — a sequential timeline for short-term continuity and a seasonal timeline that maps recurring patterns across years. This structure lets each daily forecast value stand independently, so the model can recognize and capture changes within the forecast period instead of missing them.
That independence is what makes TSF capable of producing 30-, 60-, and 90-day forecasts with measured confidence and within-period adaptability — something traditional forecasting simply can’t do.
Each day’s forecast value is selected from 800 independent forecast models — the result of combining 10 seasonal models and 2 seasonal series, each producing 40 different forecasts per combination. The system evaluates each forecast’s historical accuracy and selects the model with the strongest record of performance for that specific date.
The full TSF Engine — the foundation of all products — includes more than 25 seasonal models, each with 3 seasonal series, creating over 3,000 forecast models for monthly forecasts and another 3,000 for quarterly forecasts. Each model is evaluated objectively; none are trained or tuned subjectively.
