Label

r_{v} = \frac{views _{v}}{median _{u \in c (v), age_{u} \geq 7 d} views _{u}} y_{v} = 1 [r_{v} \geq 3]

Within a channel

Δ_{c} = \frac{1}{a _{c}} v \in A_{c} \sum y_{v} - \frac{1}{b _{c}} v \in B_{c} \sum y_{v} a_{c}, b_{c} \geq 3, a_{c} + b_{c} \leq 300

Weight

w_{c} = \frac{2 a _{c} b _{c}}{a _{c} + b _{c}}

Pooled, in points

Worked example

A guess, written down before the numbers come in: will this video do better or worse than usual? When the numbers arrive, PAX2 checks the guess against them, and every check makes the next guess sharper.
