Code for Differential Ballistic Accumulator Model

The file contains the code to replicate the study introducing the Differential Ballistic Accumulator model. The DBA is a single-process accumulator model for solving cognitive items. It is based on the idea that test-takers accumulate information to solve an item at a continuously decreasing rate and stop the process when progress is too slow. The zip file contains files to replicate the simulation study that investigates multiple estimators and two empirical examples. The study was funded by the Deutsche Forschungsgemeinschaft (DFG project number 28872689, grants RA 3453/1-2 and PO 1655/3-2).
