⚠️There's a newer version (0.11.1) of this package.Take me there.

SixSigma (version 0.9-3)

Six Sigma Tools for Quality Control and Improvement

Description

Functions and utilities to perform Statistical Analyses in the Six Sigma way. Through the DMAIC cycle (Define, Measure, Analyze, Improve, Control), you can manage several Quality Management studies: Gage R&R, Capability Analysis, Control Charts, Loss Function Analysis, etc. Data frames used in the books "Six Sigma with R" (Springer, 2012) and "Quality Control with R" (Springer, 2015) are also included in the package.
