A Modeling Toolbox and Its Applications to Statistical Process Modeling

Analyzing data that are measured or collected in processes requires statistical software. Most methods for analysis use a regression approach or its expanded forms such as polynomial and response surface models. However, the available commercial programs are inconvenient and costly for personal use, and require demanding pre-training in using them. A simple and user-friendly interface program adaptable to personal needs is therefore demanded. In this paper, a Matlab Toolbox, named the Regression Modeler (RM), is developed. The structure of the program and procedure of implementation are described. The program is verified using various datasets in process engineering. The toolbox provides users with solutions to regression models, polynomial models and response surface models with fine 2D and 3D plots.
