PEarson • Close to absolute 1 = probably correlated samples • Could be applied to moving averages? • Could we pull it into a graphite function? (Hackathon anyone?)
LIMITS OF Mathematical correlation • Requires known inputs and assumptions • Suggestion of correlation, not proof • Needs a large amount of knowledge of the data set to make decisions
LIMITS OF VISUAL CORRELATION • Takes a good eye • Hard to see the signal through the noise • Doesn’t really account for domino events • Good for trends but not as much for events
LIMITS OF EMOTIONAL correlation • Provides a trail not an answer • Depends on having a team of people • Many ideas, needs a “judge” • HUMANS (Hence Rashomoning)
