Logistic regression explained: 16 numbers to decide whether it rains tomorrow
In 43 seconds and narrated: a straight line fitted to days with and without rain gives negative probabilities on 9% of days; logistic regression passes the sum of the variables through an S-shaped curve; at a 0.5 threshold it warns about only half of the rain; if missing rain costs three times a false alarm, it catches 80%; and it promises 24% rain when it rains 20%. Muted by default: turn the sound on in the controls.
