`(1 | age)` variable in second model

[bbbales2]

The commented out model after "The former one highlights the role that state-level predictos have in accounting for structured differences among the states, while the later is closer to the rstanarm syntax"

does not have a (1 | age) term but the model after "Therefore, something like this has much fewer chances of running into computational issues than simply leaving the defaults:" does.

Not sure if this is a mistake or intentional.
