A tibble

A segment table (tibble), returned by get_segment_table.

A string. JAGS model, usually returned by make_jagscode().

One of

• "post" (default): Sample the posterior.

• "prior": Sample only the prior. Plots, summaries, etc. will use the prior. This is useful for prior predictive checks.

• "both": Sample both prior and posterior. Plots, summaries, etc. will default to using the posterior. The prior only has effect when doing Savage-Dickey density ratios in hypothesis.

• "none" or FALSE: Do not sample. Returns an mcpfit object without sample. This is useful if you only want to check prior strings (fit$prior), the JAGS model (fit$jags_code), etc.
