Model comparison for stepping and ramping spike train models - matlab code

description: Runs fitting and model comparison analyses for stepping/ramping models described in Latimer et al, Science 2015 and Zoltowski et al, Neuron 2019.

Takes in spike data observed over many trials, fits extended latent "stepping" and "ramping" (diffusion to bound) models to, and compares the model fits with the Deviance Information Criterion (DIC) or Watanabe Information Criterion (WAIC).
