Plot posterior item strengths and their uncertainty

This forest plot answers a first analysis question: which items appear stronger, and how uncertain is that ordering? Overlapping intervals mean that the data do not cleanly distinguish the corresponding strengths.

Usage

plot_strength_summary(fit, credible_mass = 0.9)

Arguments

fit

A simple BT/PL or item-SBM btsbm_fit object.

credible_mass

Width of the central posterior interval, in (0, 1).

Value

A ggplot object.
