DOE Main Effect

Problem

Estimate the main effect of a two-level factor from experimental data.

Return mean(response at level 1) - mean(response at level 0). If one of the levels never appears, return 0.0.

Hint

The main effect is a difference of group means.

case 1

in: [[0,0,1,1],[1,2,3,5]]

expected: 2.5

case 2

in: [[1,0,1,0],[4,1,6,3]]

expected: 3

case 3

in: [[0,0],[2,4]]

expected: 0

case 4

in: [[1,1],[2,4]]

expected: 0
