Extract summary statistics

summary_statistics(fit, pars, probs = c(0.05, 0.25, 0.5, 0.75, 0.95))

Arguments

fit: Stanfit object.
pars: Character vector of parameters to extract. Defaults to all parameters.
probs: Numeric vector of quantiles to extract.

Value

Dataframe of posterior summary statistics

Alternative

The tidybayes package offers an alternative to this function, for example: fit %>% tidy_draws() %>% gather_variables() %>% mean_qi(). However, this does not provide information about Rhat or Neff, nor does it process the indexes. The tidybayes package is more useful for summarising the distribution of a handful of parameters (using tidybayes::spread_draws()).
