Intermediate Data Mining extends upon the methods covered in the Basic Data Mining to build models containing multiple inputs simultaneously. This course covers multi-factor ANOVA, multiple regression, and introduces logistic regression.

Models with multiple inputs require special attention to build but offer a potentially more sensitive method to find key process input variables or model output performance. Included are logistic regression methods to model discrete outputs such as conforming/non-conforming which is particularly useful when quality problems are experienced. These methods can be used to troubleshoot processes, find potential root causes, characterize complex relationships between inputs and outputs, and even suggest optimums from observational data.

Who Should Attend

This course is designed for engineers, quality professionals, researchers, and managers who need to understand and extract information from observational data such as key process input variables or process drivers.

Learning Objectives

Through training, participants will:

  • Be able to identify key process input variables (KPIVs) or process drivers
  • Know how to model a response with multiple discrete factors
  • Know how to build multiple regression models for identification of KPIVs, characterization of complex relationships, or optimization using observational data
  • Know how to find drivers for binary response variables, such as pass/fail or conforming/non-conforming
