Model industrial data with Minitab using backward elimination – reduce predictors, detect multicollinearity

What you’ll learn
– Understand the basics of multiple regression analysis and apply it to real-world industrial data involving both continuous and categorical predictors.
– Conduct a full regression workflow including data import, exploration, matrix plots, and hypothesis testing to assess initial trends and relationships.
– Perform step-by-step backward elimination, removing non-significant predictors iteratively to simplify the model while preserving statistical integrity.
– Use adjusted R-squared and predicted R-squared to evaluate and compare the goodness-of-fit of different regression models, ensuring model validity and predictiv
– Assess model assumptions through residual analysis, including normality, homoscedasticity, and independence, using “Four-in-One” diagnostic plots.
– Execute automated backward elimination and understand its benefits compared to manual iterative elimination, especially in high-dimensional models.
– Apply best subsets regression to identify the most influential predictors under practical constraints and interpret advanced model quality parameters such as Ma

Requirements
– No Specific Prior Knowledge Needed: all topics are explained in a practical step-by-step manner.

Description
Welcome to this data-driven course from theTabtrainer® Certified Series- your trusted platform for industrial analytics and applied regression modeling.

In this course, you’ll learn to build, refine, and interpretmultiple linear regression modelsinMinitab, using a real production case from theSpeedboard Company. You’ll apply bothmanual and automated backward eliminationto identify the most relevant predictors, reduce model complexity, and maintain statistical integrity.

From correlation analysis andVIF-based multicollinearity checksto advanced model diagnostics andbest subsets regression, this training equips you to make confident, evidence-based decisions in industrial quality, R&D, and process optimization.

Analyze industrial datawith multiple continuous and categorical predictors.

Apply backward elimination, interpret p-values, VIFs, and residuals, and use best subsets regression for model simplification. Emphasis is placed on practical model optimization and real-world decision-making:
