321: Reset

The reset option erases all results from memory, and closes any open results windows, but leaves all input files and program settings unchanged. It is necessary to reset CPT if certain program settings are to be modified, and that would affect the fitted model. For example, redefining the length of the training period changes the sample data used to construct the model, and so all results need to be recalculated. However, changing the number of forecasts does not require a reset since the same model is used regardless of which and how many forecasts are to be made. CPT will automatically prompt the user if modifying a program setting would require a reset, but some menu items are deactivated (for example, setting a zero bound ) and so the user will need to reset CPT manually using the reset menu item.

The reset option becomes available only after cross-validated or retroactive forecasts have been generated.
