Before applying a ‘Best-Fit’ selection process over a given time horizon, GAINS first determines what type(s) of demand pattern(s) are applicable and then eliminates models that show statistical characteristics such as bias or volatility

1. Pattern Analysis

2. Statistical Analysis

3. Best-fit Selection

Model Plausibility

Demand Type Overrides Allow users to filter the models that should be used for a given SKUL

• Seasonal vs Non-Seasonal

The amount of history available will also automatically filter which models can be used

• Certain models require a specific number of months where there is history (e.g., SKUL history begin date is older than 6 months) before that model could be applied. For example, the year over year model

***Seasonal Models = 3,4,5,9,11,19,20,21,22,23,25
