Hi, The default results.samples have weigths associated with them, thus any statistic that needs to be calculated need to use weights. Dynesty contains the code to calcluate the mean and...

Hi, * The different sampling methods could give you somewhat different results if the MH part of sampling is not efficient and/or number of steps in the random walk is...

Hi, Thanks for a detailed question. There are multiple points/questions/possible issues here. * Run -to run variation in logZ -- that is expected to from nested sampling as relies on...

> With this, I think my original question can be considered solved. It was all a matter of using a sub-optimal configuration for my problem. Thank you for pointing me...

Pinging @joshspeagle again.

Thanks, I agree we certainly want the first run to probe "deep" enough in the posterior. My concern with the current behaviour is that it is * Not dependent on...

Hi @ColmTalbot , Thanks for the updated patches. I will try to take a look at them in next couple of weeks ( a bit busy with teaching now) Sergey

Hi, @ColmTalbot Thanks for the patches. I looked at them and I am certainly a fan of the logl insertion index statistic in particular. It would be great to have...
