Make your forecast here
The purposes with the challenge are to highlight what it means to forecast with uncertainty and collect examples of how people prefer to express uncertainty. Any way to express uncertainty is allowed, ranging from qualitative to quantitative, using probabilistic and non-probabilistic descriptions.
The participants are asked to guess their own running time and are therefore basing the forecast on best available (expert’s) knowledge. The nature of the question force them to think about uncertainty as their own, which demonstrate the subjective nature of uncertainty. Finally, participants are asked to rate their confidence in their forecasts, which is a more frequently occurring way to judge strength in predictive knowledge.
The Lundaloppet predictive challenge was previously been given 2014 with great success.
This challenge is organized by the research group UnEviL (Uncertainty and Evidence Lab) at the Centre of Environmental and Climate research and is an activity of the BECC action group: Evidence relying on simulation models and expert judgment. More info and updates at the website for the challenge
