Such\nscenarios require the experimenter to internalize the opportunity cost of\nassigning a sample to a particular experiment. We fully characterize the\noptimal policy and give an algorithm to compute it. Furthermore, we develop a\nsimple heuristic that also provides intuition for the optimal policy. We use\nsimulations based on real data to compare both the optimal algorithm and the\nheuristic to other natural alternative experimental design frameworks. In\nparticular, we discuss the paradox of power: high-powered classical tests can\nlead to highly inefficient sampling in the experiment-rich regime.","url_abs":"http://arxiv.org/abs/1805.11754v1","url_pdf":"http://arxiv.org/pdf/1805.11754v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"optimal-testing-in-the-experiment-rich-regime","repo_url":"https://github.com/schmit/optimal-testing-experiment-rich-regime","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"experimental-design","task_name":"Experimental Design"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
