Description: Bounded continuous data are encountered in many areas of
        test application. Examples include visual analogue scales used
        in the measurement of personality, mood, depression, and
        quality of life; item response times from tests with item
        deadlines; confidence ratings; and pain intensity ratings.
        Using this package, item response theory (IRT) models suitable
        for bounded continuous item scores can be fitted to data within
        a Bayesian framework. The package draws on posterior sampling
        facilities provided by R-package 'rstan' (Stan Development
        Team, 2025)<https://mc-stan.org/>. Available models include the
        Beta IRT model by Noel and Dauvier
        (2007)<doi:10.1177/0146621605287691>, the continuous response
        model by Samejima (1973)<doi:10.1007/BF03372160>, the unbounded
        normal model by Mellenbergh
        (1994)<doi:10.1207/s15327906mbr2903_2>, and the Simplex IRT
        model by Flores et al. (2020)<doi:10.1007/978-3-030-43469-4_8>.
        All models can be fitted with or without zero-one inflation
        (Molenaar et al., 2022)<doi:10.3102/10769986221108455>. Model
        fit comparisons can be conducted using the Watanabe-Akaike
        information criterion (WAIC), leave-one-out cross-validation
        information citerion (LOOIC) and the fully marginalized
        likelihood (i.e., Bayes factors).
