curtail: A package for test curtailment

A package for creating and assessing the performance of curtailed tests. A curtailed test is a variable-length test, which allows for early stopping of item administration when further items are unlikely or unable to change the final (classification) decision. The package allows for creating and assessing deterministically and stochastically (based on empirical proportions) curtailed tests. In future versions of the package, model-based stochastic curtailment may be added. The package allows for test curtailment through the creation of look-up tables, providing item-specific cut-off values for early stopping of item administration. In addition, the package allows for assessing efficiency (number of items administered to arrive at a final decision) and accuracy (concordance between the final decision based on curtailed and full-length test).
