Calculate Control Limits

Description

Calculates control limits for control charts using given data and sizes. Supports both type 1 (discrete data) and type 2 (continuous data) control charts.

Usage

calculate_limits(data, sizes = NULL, type)

Arguments

data

A numeric vector of data values.

sizes

An optional numeric vector of sample sizes. Required for type 1 charts.

type

An integer representing the type of control chart. There are two possible types: 1 for discrete data and 2 for continuous data.

Value

A list containing the lower and upper control limits, and the center.

Examples

# Example for type 2 chart with continuous data
data_values <- c(0.55, 0.60, 0.65, 0.70, 0.75)
calculate_limits(data_values, type=2)
