To solve this issue, HDDM includes a mixture model which assumes that outliers come from a uniform distribution. Here, we specify that we expect roughly 5% outliers in our data. 4

we present a novel Python-based toolbox called HDDM (hierarchical drift diffusion model), which allows fast and flexible estimation of the the drift-diffusion model and the related linear …

HDDM Model Once we have our data in the format expected by HDDM, we can now specify an HDDM model. We focus on a simple example here: a basic hierarchical model that estimates …

these new capabilities with HDDM facilitates a one-stop Bayesian-modeling pipeline for experimentalists and computational modelers interested in applying the DDM to their …

and model parameters. Here we describe a novel extension to the widely used hierarchical drift diffusion model (HDDM) toolbox, which facilitates flexible construction, estimation, and …

HDDM - hierarchical bayesian parameter estimation for the drift diffusion model ; I also have various scripts available (in matlab, Python, R, JAGS, STAN) for quantitative simulations/fits …
