Constraining a cosmology with two new coupled parameters
Posted: October 17 2016
I'm sorry if this is a trivial question, but I am just getting started with cosmomc and I am a little confused.
I have a cosmological model which basically introduces two new parameters into the Friedmann equation, call them param1 and param2. These parameters are not independent, but depend on each other in some way. I would like to constrain these parameters using Planck data.
I assume that I need to calculate and predict some parameter values which I can then constrain using cosmomc. Could anyone tell me how to go about doing this? I know that there are a few threads about adding new parameters, but I have not been able to gather how to go about coding my specific case.
Thanks in advance
