The code at the link below is the Julia package for model fitting of Evidence accumulation model for Poisson Clicks task. It will provide the Likelihood, Gradients, and Hessian matrix of the model with Automatic Differentiation. This package was built based on code written by Brunton and Brody (Brunton et al. 2013 Science). This model also includes 4 bias parameters that first introduced in pharmacological FOF inactivation study (Erlich et al. 2015 eLife).
