Friedel)Area under the curve (AUC; Myerson et al., 2001) <doi:10.1901/jeab.2001.76-235> is a popular measure used in discounting research. Although the calculation of AUC is standardized, there are differences in AUC based on some assumptions. For example, Myerson et al. (2001) <doi:10.1901/jeab.2001.76-235> assumed that (with delay discounting data) a researcher would impute an indifference point at zero delay equal to the value of the larger, later outcome. However, this practice is not clearly followed. This imputed zero-delay indifference point plays an important role in log and ordinal versions of AUC. Ordinal and log versions of AUC are described by Borges et al. (2016)<doi:10.1002/jeab.219>. The package can calculate all three versions of AUC [and includes a new version: IHS(AUC)], impute indifference points when x = 0, calculate ordinal AUC in the case of Halton sampling of x-values, and account for probability discounting AUC.https://github.com/r-universe/jefriedel/actions/runs/39559884671Mon, 23 Feb 2026 16:57:37 GMTdiscAUC1.1.0successhttps://jefriedel.r-universe.devhttps://github.com/jefriedel/discaucdiscAUC_vignette.RmddiscAUC_vignette.htmlUsing the discAUC package2021-06-03 13:33:272023-03-20 13:12:04
