Dear all,

I’m preparing a study using `rstanarm::stan_gamm4`

to model some continuous variables with splines and wanted to be sure about the output of the `rstanarm::plot_nonlinear`

. My question stems from i.a. the fact that `brms::conditional_smooths`

(invoked it seems by `brms::marginal_smooths`

) yields the conditional effects of smoothers.

My understanding is that the marginal effects would be the posterior samples without conditioning on the other covariates whereas the conditional effects are of course conditioned on the covariates. Both are interesting but inherently different, so I only want to make sure (a) I didn’t get something wrong, and (b) that we share the results we intend.

Thanks!

Cheers,

Ben

I suppose these are of little use, but anyway my session info:

- Operating System: Mac OS X Catalina
- rstanarm Version: rstanarm_2.18.2
