An end-of-life item is an item Forecaster assumes is no longer actively used in a forecast, but still exists in the data collection. When an item is identified as end-of-life, a Forecaster forecast action doesn't generate forecast results for it. An example of an end-of-life item is discontinued merchandise, a product that is no longer sold.

Logic for end-of-life:
Forecaster counts zero values at the end of historical data (trailing zeros) for a specific item. Forecaster uses this information to determine if the item is end-of-life. For an item to be end-of life, one of these must be true:

(1) There are more than 14 trailing zeros for daily data frequency.

(2) The trailing zeros exceed the forecast horizon. For example:

If your forecast horizon is three months.
And the last three months of historical data are zero for a specific item.
This is true.

(3) Forecaster counts trailing zeros if:

The last three entries for the item are zero.
If the trailing zeros are more than 10% of the total history for the item.
Then this item is end-of-life.

This logic applies to both the Prophet and MVLR algorithms.
