ppc_* are great functions for doing model checking on the data fitted. However, it would be great to also allow these function to visualize predictions in absence of any data.
Possibilites to achieve this would be
- make the
y argument optional in these functions
- expand the mcmc_* functions with things like the
x argument part of a number of ppc function (as we usually do predictions as a function of some variable x)
Generally, the x argument in the ppc functions is great and it could be available in more places.
