SBC backend using the optimizing method from rstan.

SBC backend using the optimizing method from rstan.

SBC_backend_rstan_optimizing(model, ..., n_retries_hessian = 1)

Arguments

model

a stanmodel object (created via rstan::stan_model)

...

other arguments passed to optimizing (number of iterations, ...). Argument data cannot be set this way as they need to be controlled by the package.

n_retries_hessian

the number of times the backend is allow to retry optimization (with different seeed) to produce a usable Hessian that can produce draws. In some cases, the Hessian may be numerically unstable and not be positive definite.
