Funnel of Hell #175

Closed drbenvincent closed 7 years ago

Reparameterize the hierarchical components of the models, according to the tips here: http://twiecki.github.io/blog/2017/02/08/bayesian-hierchical-non-centered/

JAGS

[x] hyperbolic + magnitude effect models
[x] hyperbolic
[x] exponential
[x] exp-power
not appropriate for non-parametric it seems

My testing has shown that this has improved MCMC chain mixing and eliminated some subtle chain pathology.
