Several papers have appeared that introduce and apply c-boxes:
Introductory paper on c-boxes with R functions and a comparison with the Imprecise Beta Model,
Comparison between c-box results and analogous Bayesian and maximum likelihood results,
Application of c-boxes in common inference problems arising in risk analysis [in preparation],
Application of the c-box for nonparametric difference in a calibration/validation study,and
See also pedagogical slide presentations and R simulations illustrating the use and performance of c-boxes in estimating distributions and their parameters. Also see expository and review papers on confidence distributions (which are special cases of c-boxes).
