Rhat values of model with chains run separately


I ran the 4 chains of my brms model separately and then I combined these chains using the function combine_models() in the package brms. I was wondering how I should check the Rhat values of this combined model; is rhat() the right way to proceed ?

Thank you!

Wouldn’t it be enough just to look at the provided \hat{R} from the output after combining them?
