      ... or you could use Python.

      AFAIK, there isn't really a Python equivalent of brms? My non-Stan workflow is to do everything in Python and then plot in R because all of the ggplot2 equivalents aren't actually equivalent, but if I use Stan it seems like I'm probably going to do my modeling in R, too :-(.

      PyStan is supposedly a thing, so maybe. Not sure if every package has python equivalent, but everyone I've seen who made the jump was much happier afterwards.

      PyStan is definitely a thing, but my understanding is that it's equivalent to RStan. I find R to be the 2nd worst language I've used (2nd only to Verilog), so I wouldn't use it if I thought I could avoid it :-).

          Is Verilog that bad? I only used it for small stuff like http://taw.github.io/ttl-cpu/

          I believe I found a race condition that will cause simulator-dependent behavior in the first block of code I looked at in the first file I opened. This isn't a knock against you, Verilog is just terribly permissive.pic.twitter.com/sh1vdQw8wB

          I don't understand - if you're using PyStan you'd be using Python and not R. They're only "equivalent" in the sense of being substitute bindings for their respective languages.

          I think someone should definitely write a brms-equivalent for Python, but if you're using brms the model is probably not too onerous to write out in the Stan EDSL-"longhand".
