Estimates the first four Western Electric Rules for detecting patterns
Calculates the iteration i'th X Chart
Calculate and plot the X, R and S Charts for variable charts
Calculates and plots variable and attributes control charts
Iteration of np control chart for attributes
P control chart for attributes
Iteration of p control chart for attributes
Calculates the i'th iteration R Chart
X chart OC Curve
The c chart control for attributes
Iteration of c control chart for attributes
Calculates the process capability
The np chart control for attributes
This is a set of statistical quality control functions, that allows plotting control charts and its iterations, process capability for variable and attribute control, highlighting the xrs_gr() function, like a first iteration for variable chart, meanwhile the we_rules() function detects non random patterns in sample.
