Methods for identifying trends in long-term effects include visualization, ladder experiment assignment, difference-in-difference, random vs constant treatment assignment, and user 'unlearning'. The long-term effects can be predicted using auto-surrogate models that forecast the long-term outcome of the experiment. ## Full article daily.dev links to this article rather than hosting it.
