WebSep 5, 2024 · In this case, we still get the benefit of CUPED, we're just getting a more reliable measurement of the 0 lift. CUPED doesn't care what the lift is, it reduces the variance of the lift measurement in all cases, if there is correlation. See the plot below of an A/A test, where the variance is reduced for 0 lift (the histogram is centered on 0): WebSep 19, 2024 · CUPED The ipython notebook for this post is up on Github.
