Description: Implements cognitive models for data from subjective
        (Likert or analog) scales and from decision making tasks with
        reaction times and choice data. Provides random generation,
        density functions, and custom response distributions for
        Bayesian estimation with 'brms', covering discrete beta,
        ordered beta and choice-confidence models for subjective
        ratings; reaction time distributions such as the ex-Gaussian
        and the shifted log-normal, Wald, gamma and Weibull; and
        sequential sampling models of choice and reaction time,
        including the drift diffusion model (DDM), the racing diffusion
        model (RDM), the lognormal race model (LNR) and the linear
        ballistic accumulator (LBA). The website provides examples and
        tutorials for using and interpreting the models. Methods are
        described in Ratcliff and McKoon (2008)
