Hi,
If i have two free parameters n1 and n2 (i am varying both and getting the marginalised probabilities for each separately), can i get the probability of (n1 -n2)? ie, the prob. distribution for the difference of two parameters n1 and n2? Is it possible to obtain this from the chains for n1 and n2?
Thanks in advance!

Re: diff of two parameters
Yes, just define a new parameter and marginalize as normal.
In CosmoMC, write your re-mapping in MapParameters of GetDist.f90 and then use map_params=T in the .ini file. There should be an example in the code.
