Statsig is proud to announce CURE, an advanced implementation of CUPED that allows customers to perform more complex regression adjustment using user-inputted categorical or numerical covariates.
This means users can run experiments even faster on Statsig, and extends the power of CUPED by making it available for new user experiments or metrics without any pre-exposure data available. This is compatible with simple adjustments to the regression - e.g. adding categorical covariates like region - or complex use cases like using predicted outcomes as a covariate.
Refer to our blog post for more information on CURE as well as the docs. This feature is currently available on Warehouse Native, and will be applied to experiments started after today. We'll be following up with CURE on Statsig Cloud.
