Hello I’m totally new on this forum.
I’m working recently with brms package and I try to modelize my data with this mixture gaussian model.
I’d like to fix intercept and linear coefficient equal for mu1 and mu2 .

I try to read documentation but I didn’t really find something about that or I didn’t understand.
Here’s my code

Thanks a lot for your answer !
I’m sorry I think I didn’t exposed my problem correctly.
I want to estimate b mu1 and b mu2 as the same parameter and then to have only one prior for both.
Same thing for intercept.
The problem to fix is then in the formula I think.
I want a mixture model not between 2 gaussian law but between the variance distribution of the same gaussian.
