Plot an SBC rank histogram

Uniform bars indicate calibration; a U shape means the posterior is too narrow (overconfident); an inverted-U means it is too wide.

Usage

plot_sbc(sbc_result, param = 1L, bins = 20L)

Arguments

sbc_result

An nsbi_sbc object from sbc().

param

Which parameter index to plot (default 1). The title uses that parameter's name (from a named prior, see prior_uniform()/ prior_normal()) when sbc() was run against a fit that has one, rendered as a plotmath symbol if the name parses as R syntax.

bins

Number of histogram bins.

Value

A ggplot object (also drawn as a side effect), invisibly.
