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).
