“…Table of equations used by factor (i.e., price or delay), mathematical operation used, shortform equation name, and long-form (i.e., full) equation used in the analyses. k was set to 1.65495 (log descriptively better fits to data than the exponentiated for some demand data (Rzeszutek, Franck et al, 2022), but descriptively better fits are not without limits. Versions of exponential decay models of demand have been successful at identifying associations between different substance use metrics (Gonz alez-Roz et al, 2019;Martínez-Loredo et al, 2021;Strickland et al, 2020;Zvorsky et al, 2019) as well as being predictive of treatment outcomes (Gonz alez-Roz et al, 2020;Schwartz et al, 2021;Secades-Villa et al, 2016).…”
