ans_dd

Converts answers from 5.5 trial delay discounting from Qualtrics template

Facilitates some of the analyses performed in studies of
behavioral economic discounting. The package supports scoring of the 27-Item Monetary Choice
Questionnaire (see Kaplan et al., 2016; <doi:10.1007/s40614-016-0070-9>), calculating k
values (Mazur's simple hyperbolic and exponential) using nonlinear regression, calculating
various Area Under the Curve (AUC) measures, plotting regression curves for both fit-to-group and
two-stage approaches, checking for unsystematic discounting
(Johnson & Bickel, 2008; <doi:10.1037/1064-1297.16.3.264>) and scoring of the
minute discounting task (see Koffarnus & Bickel, 2014; <doi:10.1037/a0035973>) using the
Qualtrics 5-trial discounting template (see the Qualtrics Minute Discounting User Guide;
<doi:10.13140/RG.2.2.26495.79527>), which is also available as a .qsf file in this package.
