Regression Methods and Models (Training)


This session explores some of the most widely known modelling techniques. We will discuss when regression methods are appropriate and how to understand and select the variables that go into your model. The difference between data types will be discussed and how this influences the model will be described. While linear and binomial logistic regression models are the most commonly used, other models will be discussed.
