New values can be forecasted using
the existing values in Serial columns.
Any columns can be set to Serial type by moving to the
column and pressing enter to open the
Grid edit dialog.
The Serial type is also available on the right click
menu. This type of column is the same as an Input
column but is also used as an Output column during
forecasting. If a Serial column is available the
Forecast Action is enabled. This produces the Forecast
dialog. When the dialog is completed the forecasting
process begins. Forecasting can take a long time if
many Serial columns are used or if the Grid has many
rows. The process first creates a number of extra
Engaged rows. These working locations are used while
forecasting runs. They cannot be edited. Forecasting
creates neural networks for testing as it runs. When
forecasting has finished the extra rows will be changed
to Forecast or Risk and will contain the forecasted
values. The estimated risk of the forecast is the
number of times the forecast values had to be adjusted
before the neural network gave a similar error to that
produced prior to the forecast. Forecast rows can be
used in subsequent forecasts.
