Degeneracy diagnostics for dynamic model

[hyunjimoon]

@jandraor could we use this thread to sync stanify feature implementation for degeneracy diagnostics for dynamic (nonlinear model) in python and R? Attached is my summary which includes self-consistency from section1 of sbc paper and comparison with Michael's posterior z-score.

@martinmodrak wrote the most inclusive summary for Runtime warnings and convergence problems, thanks!

will list examples of inferential degeneracy (e.g. between social and economic factors) of empirical research from impossibility of perfectly controlled. this leads to inseparability and indeterminacy of most reported causal effects

• dose entrepreneurship majorly depend on nature (risk-loving, tenacity, agility) or nurture (junior high, diploma, expensive program (director, network)) or the former invoked by the later (knowing entrep. invokes latent entrepreneurial nature). this "invoke (to become entrep)"is known to have affect affect on the very first exposure
• does chronic waste disease majorly depend on social factors (network structure, closeness during mating season) or biological factors (diffusion rate of e.g. virus, disease)
