Hi, everyone,
I want to use the Planck2018 and Pantheon datasets to constrain the CLP dark energy model with w = w0_fld + wa_fld*(1-a). I set w0_fld = -0.9, wa_fld = 0.0 in **explanatory.ini** and mo…

Hi, I'm running into an issue with george and emcee. My likelihood function involves a call to gp.predict. This is fast in serial, but when I try to run emcee with a multiprocessing Pool, each gp.pred…

Hello,
I have a naive question...
I want to be able to pull a PDB File out every few steps or so (for some clustering/checking forces on ligand/etc).
For instance, when using a standard OpenM…

I have downloaded the multichain_mcmc package and have tried out the majority of samples in the multichain_mcmc dream_examples folder. All of them result in error messages:
Python 2.7.3 (v2.7.3:70274…

We can't get new patches into samplers because there aren't any reliable tests.
We need tests for the samplers for
- [ ] accuracy on means
- [ ] accuracy on variances
- [ ] speed regression tests
We…
