%description
Simulation-based evidence accumulation models for analyzing responses and
reaction times in single- and multi-response tasks. The package includes
simulation engines for five representative models: the Diffusion Decision
Model (DDM), Leaky Competing Accumulator (LCA), Linear Ballistic
Accumulator (LBA), Racing Diffusion Model (RDM), and Levy Flight Model
(LFM), and extends these frameworks to multi-response settings. The
package supports user-defined functions for item-level parameterization
and the incorporation of covariates, enabling flexible customization and
the development of new model variants based on existing architectures.
Inference is performed using simulation-based methods, including
Approximate Bayesian Computation (ABC) and Amortized Bayesian Inference
(ABI), which allow parameter estimation without requiring tractable
likelihood functions. In addition to core inference tools, the package
provides modules for parameter recovery, posterior predictive checks, and
model comparison, facilitating the study of a wide range of cognitive
processes in tasks involving perceptual decision making, memory retrieval,
and value-based decision making. Key methods implemented in the package
are described in Ratcliff (1978) <doi:10.1037/0033-295X.85.2.59>, Usher
and McClelland (2001) <doi:10.1037/0033-295X.108.3.550>, Brown and
