Hi, I have a couple concerns.
First, rstanarm (and rstan in general) spews out a ton of output, every 10% of iterations in each chain, the elapsed time, just lots of crap which as a user I’d rather not see. Maybe if it’s gonna take more than a few seconds it would be good to have one or two lines of output so that the user won’t freak out. But all these screenfuls, that too much.
Second, I wonder if we could change the header of print output to be more similar to what lm/glm does.
Here’s an example.
lm(formula = post_test ~ treatment, data=electric, subset=(grade==4))
family: gaussian [identity]
formula: post_test ~ treatment
I prefer the way lm does it, because sometimes we’re just looking at the print output and it’s very helpful to see the name of the data frame and any subsetting.
