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.
