limits.beta {bcc}R Documentation

Limits for discrete data

Description

These function are used to compute the upper and lower control limits.

Usage

limits.beta(center, std.dev, sizes, conf)

Arguments

center

sample/group center statistic.

std.dev

within group standard deviation.

sizes

sample sizes.

conf

a numeric value used t o comput control limits, specifying the confidence level (0 < conf < 1)

Value

The function limits.beta returns a matrix with lower and upper control limits.

Examples

data(Montgomery2005)
limits.beta(center = 0.2313333, std.dev = 0.421685, sizes = Montgomery2005$Sample, conf = 0.9)
