Internal function that creates a formatted log message describing the sampling parameters. The message format varies by method, with different information shown for exact sampling vs approximate methods (VB, Laplace, Pathfinder). Optionally includes time steps and forecast horizon if present.
Arguments
- args
List of stan arguments containing:
object: Stan model object (CmdStanModel or stanmodel)
For sampling method: iter_sampling, iter_warmup (cmdstanr) or iter, warmup (rstan), chains
For vb method: iter, trials, output_samples
For laplace method: trials
For pathfinder method: trials, draws
data: List potentially containing t (time steps) and horizon (forecast)
- method
Character string indicating the sampling method. One of "sampling" (exact MCMC), "vb" (variational Bayes), "laplace" (Laplace approximation), or "pathfinder" (pathfinder algorithm).
