SciCast’s unique feature is the ability to make conditional edits, also called assumptions or combinatorial edits. Now you’ll have a chance to compete for big prizes for yourmaking at least at least 25% of your forecasts conditional forecasts. combo edits!Continue reading →
Q: Expected value? So, if I’m betting that A happens, shouldn’t I just make P(A)=99%?
A: If you knew exactly when we would calculate the expected value, this would be a profitable strategy. But (a) we will randomize, and (b) we have selected questionsmany questions are still likely to resolve, so there is some risk.
We’re thrilled to announce that everyone who participated in the accuracy contest will receive an invitation to be a guest star on Survivor: Future! Can you outwit the other castaways with your prediction power?
Please give us a hand with our research and take a moment to complete the latest surveys. On April 10, to thank you for your help, we’ll be conducting random drawings for $1,000 total in Amazon Gift Cards. You earn one ticket for each of these five surveys completed sensibly. Previous completions count. We will not ask for any personally identifying information and we strictly follow human subjects in research protocols.
The post Analysis of SciCast Safe Mode Usage has been revised slightly to use a power law (x^k) instead of a logarithmic function (k ln x). This is because the logarithmic function could go negative, which the percentage of trades cannot do. Revisions are inred.
Note: The following post has been revised slightly to use a power law (x^k) instead of a logarithmic function (k ln x). This is because the logarithmic function could go negative, which we know the percentage of trades cannot do. Revisions are in red.
Given the ease of switching back and forth between Safe Mode and Power Mode, we were interested to observe the relative use of each mode. (For a description of the different modes, see the Appendix.) Continue reading →
The Recommender survey has closed, and results are in! Of the 37 survey participants, 59% perceive the Recommender provides recommended questions of interest about as often as if they were drawn randomly from the roughly 600 on the site. Continue reading →
The SciCast Accuracy Incentives contest has come to an end. The final accuracy leaderboard will be selected at a random time in the next few weeks. This will allow more questions to resolve as well as randomize the selection time to reduce the impact of attempts to inflate scores on unresolved contest questions.
