Plot the course of a CAT session

An interactive plotly chart in two panels side by side: the standardized ability estimate and its standard error after each answer, across the whole test, one colour per scale. Hovering a point shows the statement and the answer; a dashed line marks the standard error at which a scale stops.

Usage

plot_cat_trajectory(s)

Arguments

s

A CAT session with at least one answer (see cat_start).

Value

A plotly htmlwidget.

while (s$stage == "testing") s <- cat_answer(s, sample(1:5, 1))
