Individual-observation chart for bounded data

Usage

edetect_x(x, bounds, center = NULL, phase1 = NULL, ...)

Arguments

x: Phase II observations.
bounds: Known bounds of the observations.
center: Pre-change mean; omit to estimate it from phase1.
phase1: Optional Phase I observations.
...: Passed to edetect_design() (arl, direction, type, evalue, delta, weights).

Value

An edetect_chart.

Examples

set.seed(2)
x <- c(runif(40, 0.3, 0.7), runif(40, 0.5, 0.9))
chart <- edetect_x(x, bounds = c(0, 1), center = 0.5, arl = 200)
#> Warning: Alarm at t = 50; 30 later observations were not consumed.
