observed_band: Add a band corresponding to the observed number of...

In heike/vinference: Inference under the lineup protocol

Description

This function adds a band to assist in the visual estimation of alpha from evaluated lineups.

Usage

observed_band(obs, limits, c = m0/K, m0 = 19, K = 30)

Arguments

obs	Observed number of "c-interesting" panels (panels with at least c selections). If NA, the line is omitted.
limits	Lower and upper bounds for number of panels. If NA, the bands are omitted.
c	The number of selections a panel must have to be interesting (can be non-integer)
m0	The number of null panels in the lineup
K	The total number of null panel selections (or, in a Rorschach lineup, the total number of evaluations)

Examples

estimate_alpha_visual() + observed_band(obs = NA, limits = c(5, 7))
estimate_alpha_visual() + observed_band(obs = 6, limits = NA)
estimate_alpha_visual(c = 1, m0 = 19, K = 50) + 
  observed_band(obs = 6, limits = c(4, 8), c = 1, m0 = 19, K = 50)
