⚠️There's a newer version (1.55) of this package.Take me there.

qualityTools (version 1.31.1)

Statistical Methods for Quality Science

Description

This is a package for teaching statistical methods in the field of Quality Science. It covers distribution fitting, process capability, Gage R&R, factorial, fractional factorial design as well as response surface methods including the use of desirability functions. Define - Pareto Chart; Measure - Probability and Quantile-Quantile Plots, Process Capability Ratios for various distributions and Gage RR Analyze i.e. Pareto Chart, Multi-Vari Chart, Dot Plot; Improve - Full and fractional factorial, response surface and mixture designs as well as the desirability approach for simultaneous optimization of more than one response variable. Normal, Pareto and Lenth Plot of effects as well as Interaction Plots; Control - Quality Control Charts can be found in the qcc package. The focus is on teaching the statistical methodology used in the Quality Sciences.
