Combining Information from Multiple Forecasters: Inefficiency of Central Tendency

Ville A. Satopää

Even though the forecasting literature agrees that aggregating multiple predictions of some future outcome typically outperforms the individual predictions, there is no general con…

Bayesian aggregation of two forecasts in the partial information framework

Philip Ernst, Robin Pemantle, Ville Satopaa +1

We generalize the results of \cite{SPU, SJPU} by showing how the Gaussian aggregator may be computed in a setting where parameter estimation is not required. We proceed to provide…

Combining and Extremizing Real-Valued Forecasts

Ville Satopää, Lyle Ungar

The weighted average is by far the most popular approach to combining multiple forecasts of some future outcome. This paper shows that both for probability or real-valued forecasts…

Partial Information Framework: Model-Based Aggregation of Estimates from Diverse Information Sources

Ville A. Satopää, Shane T. Jensen, Robin Pemantle +1

Prediction polling is an increasingly popular form of crowdsourcing in which multiple participants estimate the probability or magnitude of some future event. These estimates are t…

Probability aggregation in time-series: Dynamic hierarchical modeling of sparse expert beliefs

Ville A. Satopää, Shane T. Jensen, Barbara A. Mellers +2

Most subjective probability aggregation procedures use a single probability judgment from each expert, even though it is common for experts studying real problems to update their p…

Modeling Probability Forecasts via Information Diversity

Ville A. Satopää, Robin Pemantle, Lyle H. Ungar

Randomness in scientific estimation is generally assumed to arise from unmeasured or uncontrolled factors. However, when combining subjective probability estimates, heterogeneity s…
