BART In STAN

Modeling
1

I am trying to define a function ‘bart_rng’ in STAN that can generate samples from Bayesian Additive Regression Trees (BART) prior and a function ‘dbart’ that gives me probability density at a point given the parameters of BART. Does Stan have any in-built functions or can you help me in building one?

Check out GitHub - vdorie/stan4bart: Uses Stan sampler and math library to semiparametrically fit linear and multilevel models with additive Bayesian Additive Regression Tree (BART) components.
