An easy introduction to Regression in Data Analysis
Learning and applying new methods and techniques can often be a daunting experience.
This class is designed to provide you with a compact, and easy to understand, class that focuses on the basic principles of regression in data analysis.
This class will focus on the understanding and applying linear regression in data analysis
This class will explain what regression is and how Ordinary Least Squares (OLS) works. It will do this without any equations or mathematics. The focus of this class is on application and interpretation of regression in data analysis. The learning on this class is underpinned by many animated graphics that demonstrate particular concepts.
No prior knowledge is necessary and this class is for anyone who would like to engage with quantitative analysis.
