Any calibrated model can be decomposed by implementing four S3 methods that run the model, summarize its output, and construct counterfactual inputs. Counterfactuals either remove a factor entirely or hold it at its value in a baseline year, and a sequential decomposition attributes each year's policy conditional on the past.https://github.com/r-universe/aucarter/actions/runs/41836095884Tue, 03 Nov 2026 17:25:50 GMTshapleydecomp1.0.0successhttps://aucarter.r-universe.devhttps://github.com/aucarter/shapleydecompshapleydecomp.Rmdshapleydecomp.htmlGet started2026-10-13 21:29:272026-10-14 23:17:28methods.Rmdmethods.htmlMethods2026-10-13 20:48:082026-10-21 23:17:09
