beezdemand - Behavioral Economic Easy Demand
Facilitates many of the analyses performed in studies of
behavioral economic demand. The package supports commonly-used
options for modeling operant demand including (1) data
screening proposed by Stein, Koffarnus, Snider, Quisenberry, &
Bickel (2015; <doi:10.1037/pha0000020>), (2) fitting models of
demand such as linear (Hursh, Raslear, Bauman, & Black, 1989,
<doi:10.1007/978-94-009-2470-3_22>), exponential (Hursh &
Silberberg, 2008, <doi:10.1037/0033-295X.115.1.186>) and
modified exponential (Koffarnus, Franck, Stein, & Bickel, 2015,
<doi:10.1037/pha0000045>), (3) calculating numerous measures
relevant to applied behavioral economists (Intensity, Pmax,
Omax), (4) nonlinear mixed-effects demand models with
subject-level random effects, fit either with 'nlme' or with a
'TMB' backend that also provides a two-part (hurdle) model for
zero-inflated consumption, and (5) Monte Carlo power analysis
for condition differences in demand parameters. Also supports
plotting and comparing data.
