  • This PR takes care of initial values setting for chains.
  • The t and p_outlier parameters will consistently start at a very low value to pre-empt computational issues with gradients on the analytical DDM likelihood
  • The nuts_numpyro sampler setting now respects initial values and jitter can be turned off
  • Strange prior settings when log_logit links were chosen are now fixed
  • Convenience function is added to allow manual jittering of starting points
  • Default group distribution of t parameter changed to Gamma distribution
