Example Stan Fit

Source: R/imuGAP-package.R
fit_sim.Rd

A reference imugap_fit object produced by running sampling() on the bundled locations_sim, populations_sim, and observations_sim datasets. Intended as a lightweight fixture for examples, tests, and downstream tooling that needs a real fit without paying the cost of recompiling or re-running the Stan model.

Format

An object of class imugap_fit as returned by sampling().

Details

Generated with the same minimal sampler settings as the smoke test:

  • iter = 100

  • chains = 1

  • seed = 1L

  • refresh = 0

These settings are not enough for convergence; fit_sim is a wiring fixture, not a scientifically meaningful posterior. It is not tracked in git: it is regenerated on build by data-raw/fit_data.R (run just data-fit locally, or just data for the full pipeline).

Note that underlying backend fit objects bundle references to the compiled Stan model and can be sensitive to major version changes in rstan and StanHeaders. If a future install fails to load fit_sim, regenerate it via data-raw/fit_data.R.
