Best Practices for Translating BUGS into Stan

• Read Appendix B "Stan for Users of BUGS" and Appendix C "Stan Program Style Guide" in Stan Modeling Language User's Guide and Reference Manual
• Don't use InvGamma(,) as a default scale prior. See Gelman (2006) for discussion and examples.
• Use weakly informative priors. See, e.g., Sections 5.2, 5.11, 5.12, and many other examples in Stan Modeling Language User's Guide and Reference Manual
