Exhibit
Options
- ADownsample the data uniformly to reduce the amount of data.
- BCreate two different models for different sections of the data.
- CDownsample the data in sections where Price < 50.
- DOffset the input data by a constant value where Price > 50.
- EExamine the input data, and apply non-linear data transformations where appropriate.
- FUse a non-linear model instead of a linear model.
