Response Rate Uplift by Decile

Problem

Compute the response-rate uplift per decile: the decile response rate minus the overall response rate, using the same sorting and chunking as decile rates.

Empty input returns [].

Hint

Uplift compares each decile's response against the base rate.

Test cases

case 1

in: [[1,0,1,0,1,0,1,0,1,0],[0.9,0.8,0.7,0.6,0.5,0.4,0.3,0.2,0.1,0]]

expected: [0.5,-0.5,0.5,-0.5,0.5,-0.5,0.5,-0.5,0.5,-0.5]

case 2

in: [[1,1,0,0],[0.9,0.8,0.7,0.6]]

expected: [0.5,0.5,-0.5,-0.5]

case 3

in: [[],[]]

expected: []
