I will fix this. Emcee used to work, albeit slowly. Experimental idea is to emcee a few steps and then optimize from the highest likelihood one, in order to solve the initialization of a non-linear op…

The "Informational Message" that's currently in Stan confuses users.
Proposals so far:
- remove message from warmup

31ca5d4d40469d737cc03bf128c2d44831556411 added the ability to condition continuous ERPs with equality. It works by setting the ERP in the condition call directly. This does the right thing with Metrop…

Hi,
I am wondering if you have any experience on using EMCEE to fit regressions with many predictors. I am needing something efficient for a regression of the form
y = XB + Zu ... typical mixed-model.…

We should have an adaptive metropolis sampler.
@fonnesbeck Do you think this should be a release blocker?

I'm comparing MH vs GW for sampling a 1D unit Gaussian likelihood. For MH I use a proposal covariance of 2.4**2. For GW I do 100 walkers and initialize them by drawing samples from the unit Gaussian. …
