hBayesDM-package: Hierarchical Bayesian Modeling of Decision-Making Tasks

Description Author(s) References See Also

Description

Fit an array of decision-making tasks with computational models in a hierarchical Bayesian framework. Can perform hierarchical Bayesian analysis of various computational models with a single line of coding. Bolded tasks, followed by their respective models, are itemized below.

Bandit

2-Armed Bandit (Rescorla-Wagner (delta)) — bandit2arm_delta
4-Armed Bandit with fictive updating + reward/punishment sensitvity (Rescorla-Wagner (delta)) — bandit4arm_4par
4-Armed Bandit with fictive updating + reward/punishment sensitvity + lapse (Rescorla-Wagner (delta)) — bandit4arm_lapse
