Description: 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>), and (3) calculating numerous
        measures relevant to applied behavioral economists (Intensity,
        Pmax, Omax). Also supports plotting and comparing data.
