At the heart of the golden rule of forecasting is that you should be conservative; forecasters must seek all knowledge relevant to the problem and use methods that have been validated for the situation.
With “be conservative” as the overarching golden rule, the authors performed extensive research to develop a list of guidelines that help lead to good forecasts and identified practices that generate poor decisions. Continue reading “The heart of good forecasting: Be conservative”
