Perhaps you should try some spelling variations:
"out-of-example forecasting" » "out-of-examples forecasting", "out-of-sample forecasting", "out-of-simple forecasting"
"out-of-example forecasts" » "out-of-sample forecasts", "out-of-sample forecast", "out-of-examples forecasting"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"out-of-example forecasts\") OR (\"out-of-example forecasting\"))".
• Removing quotes may allow a broader search: (( out-of-example forecasts ) OR ( out-of-example forecasting )).
• Adding a wildcard symbol may retrieve word variants: (("out-of-example forecasts") OR ("out-of-example forecasting"))*.
