Did you have any specific comment? I have exactly the same problem... :) essentially how to model processes with a (partially, at least) negative ACF. Stefano

My first, naive, feeling is only that mathematically it could work, however by itself a negative kernel is probably not a kernel, at least according to Eq. 4.2 in Rasmussen...

Thanks! Good to know. A kind suggestion. Adding to the docs an example with a properly written prior using george could anyway be useful, I think. Bye, Stefano

My bet would be something like: FWHM = 2 \* sqrt ( ln(2) \* (x2 + y2)) where x2 and y2 are the second order moment (assuming Gaussian shape, etc....

I was cryptic. Sorry for that. What I mean is simply that it happens, in a time-series, to have upper limits (or even lower limits, in principle, if we are...

Let's assume, for instance, we have ten magnitude measurements. And nine of them are just upper limits, i.e. nothing is detected. One of them gives a measurement brighter than the...

Hi Jason, Sure. I'd suggest to try the first example reported in this nice post by Dan Foreman-Mackey: https://dfm.io/posts/intro-to-numpyro/ I found two problems. The first is simply that the samples...

Hi Jason, I tried this (in attachment). Please, let me know if something is not clear. I hope it might help. Stefano Il giorno gio 8 giu 2023 alle ore...

Hi Jason, I don't kowm, actually. I attach the notebook again. Please, let me know if you can get it. Bye, Stefano Il giorno lun 12 giu 2023 alle ore...

Actually, the system does not allow me to attach anything. I did not know that. So I just list the code below! Else, this is the link to colab: https://colab.research.google.com/drive/1hlmnjIftdsO9SyeHzDaXmHtDvszTeh35?usp=sharing...
