WebSep 24, 2024 · We can now implement our CUPED methods. Firstly, we need to calculate a constant (theta) which will be applied to each cookie_id unit. The constant we apply is the covariance exhibited between the ... 1) Pick a pre-experiment covariate (X). The covariate should be highly correlated with the experiment’s north star metric (Y) and should not be impacted by experiment treatments. Often, the best covariate is the north star metric prior to the experiment period. 2) Calculate the CUPED-adjusted metric (Ŷ) for each … See more Ok, let’s pump the brakes a bit and try to understand what’s happening.
