Hello,I'm running a quintessence dark energy model with extra radiation before recombination. I'm compiling such a model with full CMB ( TT+TE+EE+LowE+lensing) in CosmoMC and the value of H0 seems to...

If you only allow Neff > 3.044 then yes it should normally increase H0 at fixed Planck data in LCDM+Neff model (faster expansion -> shorter time to recombination -> smaller sound horizon...

The background equations are also used in derivs() for the perturbations. However, if the background Einstein equation changes, usually the perturbed one does as well, so you'd need to modify the...

The minimizer can be a bit unstable. It will likely work better if you provide a covmat from a chain, then it will know about degeneracies etc.The difference in "chi2" is likely priors.Statistics:...

You can try tools like tracemalloc to diagnose. Cobaya memory will gradually increase as it stores more points, but not to an extent that it is likely to be a problem.Statistics: Posted by Antony...
