Prediction

Philip Tetlock and Dan Gardner promote 10 key themes that have been experimentally demonstrated to improve prediction accuracy. These themes are:
- 1) Triage
- 2) Breaking problems down
- 3) Balance Inside and Outside Views
- 4) Update your Beliefs
- 5) Everything is Connected
- 6) Remove Uncertainty
- 7) Balance Prudence and Decisiveness
- 8) Learn from Failure and Success
- 9) Manage the team
- 10) Master the error-balancing bicycle



10 themes for Superforecasting

A city's transportation department is considering adding a new bus line. Two planners present their forecasts for its potential ridership:

*   **Planner A:** "My cousin started taking the bus last year and loves it. People are tired of driving. I predict this new line will be immediately popular and serve 5,000 riders per day within the first month."
*   **Planner B:** "Surveys on the proposed route show high interest from 20% of residents. Similar lines in three comparable cities saw a 5-8% ri

Evaluating a Business Sales Forecast

A prediction problem in statistical learning occurs when there are a significant number of observations and their corresponding outcomes, and the goal is to predict outcomes for a new set of observations where they are unavailable. Let $$X$$ be the set of all input variables and $$Y$$ be the set of corresponding outcomes. If $$\hat{f}$$ is the estimate of the function $$f$$ that maps $$X$$ to $$Y$$, and $$\hat{Y}$$ is the resulting prediction of $$Y$$, assuming the error term averages to zero ($$\bar{\epsilon}=0$$), the following holds:

$$Y=f(X)+\epsilon, \bar{\epsilon}=0 \implies \hat{Y}=\hat{f}(X)$$
