Confirmation by Robustness Analysis: A Bayesian Account

Abstract Some authors claim that minimal models have limited epistemic value (Fumagalli, 2016; Grüne-Yanoff, 2009a). Others defend the benefits of modelling by invoking role robustness analysis for hypothesis confirmation (see, e.g., Levins, 1966; Kuorikoski et al., 2010) but such arguments find much resistance Odenbaugh & Alexandrova, 2011). In this paper, we offer a Bayesian rationalization and defence view can play confirmatory role, thereby shed light on potential confirmation. We illustrate our argument reference to case study from macroeconomics. At same time, also show there are cases in which is detrimental characterize these link them recent investigations evidential variety (Landes, 2020b, 2021; Osimani Landes, forthcoming). conclude over confirm, its depends concrete circumstances.
