Recently, much success has been witnessed in the development of distributionally robust optimization (DRO), which considers the worst-case expected recourse function under the least favorable probability distribution from a distributional family. However, in the presence of endogenous outliers such that their corresponding recourse function values are very large or even infinite, the commonly used DRO framework alone tends to overemphasize these endogenous outliers and cause undesirable or even infeasible decisions. On the contrary, distributionally favorable optimization (DFO), concerning the best-case expected recourse function under the most favorable distribution from the distributional family, can serve as a proper measure of the stochastic recourse function and mitigate the effect of endogenous outliers. We show that DFO recovers many robust statistics, suggesting that the DFO framework might be appropriate for the stochastic recourse function in the presence of endogenous outliers. A notion of decision outlier robustness is proposed for selecting a DFO framework for data-driven optimization with outliers. We also provide a unified way to integrate DRO with DFO, where DRO addresses the out-of-sample performance, and DFO properly handles the stochastic recourse function under endogenous outliers. We further extend the proposed DFO framework to solve two-stage stochastic programs without relatively complete recourse. The numerical study demonstrates that the framework is promising.<\/jats:p>","DOI":"10.1137\/22m1528094","type":"journal-article","created":{"date-parts":[[2024,1,29]],"date-time":"2024-01-29T04:32:52Z","timestamp":1706502772000},"page":"419-458","source":"Crossref","is-referenced-by-count":11,"title":["Distributionally Favorable Optimization: A Framework for Data-Driven Decision-Making with Endogenous Outliers"],"prefix":"10.1137","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4231-2179","authenticated-orcid":true,"given":"Nan","family":"Jiang","sequence":"first","affiliation":[{"name":"H.
