Segmentation and Clustering
Skills Covered: Variable Reduction, Clustering Models Design, Alteryx, Variable Reduction, Principal Components Analysis (PCA)
ABOUT THIS COURSE
In the Segmentation and Clustering course, you will gain the foundational knowledge to build and apply clustering models to develop more sophisticated segmentation in business contexts. You will be able to apply the key concepts of segmentation and clustering, such as standardization vs. localization, distance, and scaling as well as concepts of variable reduction and how to use principal components analysis (PCA) to prepare data for clustering models. You will also learn how to choose between hierarchical and k-centroid clustering models and how to build and apply k-centroid clustering models. This course will provide you with the techniques to apply your knowledge in a data analytics program called Alteryx.
This course is part of the Business Analyst Nanodegree Program.
