Events
3,659
PrecisionHow precisely timestamps are recorded — second-level is best, day-level is coarsest.
day-level
Branching RatioHow much events trigger other events. 0 = all independent, 1 = all triggered by prior events.
0.988
IndependentPercentage of events that happened on their own — not triggered by a previous event.
0.7%
Half-lifeHow quickly the triggering effect decays. Short half-life = rapid-fire copycats. Long half-life = slow-burn social spread.
29.9 days
99.3% of events in this dataset were triggered by prior events. Only 0.7% are independent (25 of 3,659).
Data Quality Notes
- •29.9-day half-life — slowest contagion decay in the study
- •Only 25 independent reports out of 3,659 total
- •cloud_cover rounded to nearest 10% in 76% of records
- •precip_intensity duplicates precip_probability in 51% of rows
If You're Using This Dataset
Known Issues
- •cloud_cover 76% at round numbers (heaping)
- •precip_intensity = precip_probability in 51% of rows
Key Insight
The most self-exciting dataset in the study. Only 25 of 3,659 Bigfoot reports are independent events.
