Problem appears upstream to Distributions.jl, see https://github.com/JuliaStats/Distributions.jl/issues/650
The following code:
```

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…

When derivatives of the objective function are available, MCMC methods that use them, for example Hamiltonian Monte Carlo, can be very much faster than MCMC methods that aren't. PINT has gone to great…

This is an FYI / guidance for those who are currently running `cmdstanpy>=1.0.2`, specifically when doing full MCMC sampling (`mcmc_samples > 0`). We've noticed that `cmdstanpy` now logs warnings fair…

#### Summary:
The number of log prob gradient evaluations per sample is one greater than the reported `n_leapfrog` for that sample.
This does not need to be so; the gradient for the starting point w…

### What is the problem this feature will solve?
I am using Astropy models in MCMC and this would be a useful feature. For example, if I am running an MCMC with my model being two gaussians. The post…

I ran 50000 steps with the Planck-2018 TT data firstly without a covariance matrix and got an abysmal acceptance rate of ~0.01.
During this run, it often gave this message ("failed to calculate covar…

When MCMC/CD/SAN/etc. total step count (i.e., sample size * interval) exceeds the maximum signed integer value (2147483647), it produces a signed integer overflow resulting in funny diagnostic output …
