Extensive research of Taguchi method
Project Year: Apr 2015 - Mar 2018
Systematic theorization of Taguchi method
Project Year: Apr 2012 - Mar 2015
Taguchi method is widely used in practice by engineers in the world. Taguchi method is the collection of procedures which Dr. Gen-ichi Taguchi had been developing for years.Particularly, Taguchi method consists of (i) robust parameter design based...
Theoretical studies on Taguchi methods and their applications
In this research, we investigated the mathematical aspects of Taguchi method. Especially, we studied on the following four topics : i) statistical inference of SN ratio, ii) analysis of orthogonal array, iii) online quality control, iv) theoretica...
Sample size determination for procedures of design of experiments and multivariate analysis
In this research, we dealt with multiple comparison procedures and Mahalanobis Taguchi system(MT system). We investigated their performance from the view points of sample size determination and proposed several new procedures.Firstly, we investiga...
Statistical Models for Causal Inference
In this research, statistical inference procedures of causal diagram using graphical modeling and covariance structure analysis are discussed. We formulate the causal interpretation and outline the proper use of structural equation model and poten...
