- Understanding Rare Events and Anomalies: Why streaks patterns change - Jan 8, 2016.
We often look back at the past year and an overall history of rare events, and try to then extrapolate future odds of the same rare event, based on that. We illustrate here, that rare past events have no usefulness in understanding the rarity of the same events in the future!
