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

limits.beta.p(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 (if 0 < conf < 1)

...

further arguments are ignored.

Value

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

Examples

limits.beta.p(center = 0.9989597, std.dev = 0.0009362578, conf = 0.9)
