Description


Description

The course explains one of the important aspect of machine learning – Principal component analysis and factor analysis in a very easy to understand manner. It explains theory as well as demonstrates how to use SAS and R for the purpose.

The course provides entire course content available to download in PDF format, data set and code files. The detail course content is as follows.

Intuitive Understanding of PCA 2D Case
what is the variance in the data in different dimensions?
what is principal component?
Formal definition of PCs
Understand the formal definition of PCA
Properties of Principal Components
Understanding principal component analysis (PCA) definition using a 3D image

Properties of Principal Components
Summarize PCA concepts
Understand why first eigen value is bigger than second, second is bigger than third and so on
Data Treatment for conducting PCA
How to treat ordinal variables?
How to treat numeric variables?
Conduct PCA using SAS: Understand
Correlation Matrix
Eigen value table
Scree plot
How many pricipal components one should keep?
How is principal components getting derived?
Conduct PCA using R
Introduction to Factor Analysis
Introduction to factor analysis
Factor analysis vs PCA side by side

Factor Analysis Using R
Factor Analysis Using SAS
Theory for using PCA for Variable Selection
Demo of using PCA for Variable Selection

Who this course is for:

Analytics Professionals
Research Scholars
