Load the bundled simulated SBT maximum-likelihood fit

Returns the full fitted example used by the model article. The fit contains the same simulated data returned by sbt_example_data() and has no MCMC posterior attached.

Usage

sbt_example_fit(rebuild = TRUE)

Arguments

rebuild

Passed to sbt_fit_read(). Use FALSE when only the portable fit contents are needed.

Value

An optimised sbt_fit() for the bundled simulated example, including its processed data, resolved configuration, accepted MLE, diagnostics, and validation record. It does not contain posterior draws.
