Monotonic Binning Check

Problem

Check whether a sequence of WOE values is monotonic: either non-decreasing or non-increasing throughout.

Sequences with fewer than two values return True.

Hint

Monotonic WOE across bins is a common scorecard requirement.

case 1

in: [[0.1,0.2,0.3]]

expected: true

case 2

in: [[0.3,0.2,0.1]]

expected: true

case 3

in: [[0.1,0.3,0.2]]

expected: false

case 4

in: [[]]

expected: true

case 5

in: [[0.5]]

expected: true
