Exam PA Study Guide, Fall 2020
20 September, 2020
This is the study guide for ExamPA.net, the online course for the SOA’s Predictive Analytics exam.
While meeting all of the learning requirements of Exam PA, this 200-page study guide gives you data science and machine learning training. You will learn how to get your data into R, clean it, visualize it, and use models to derive business value. Just as a scientist sets up lab experiments to form and test hypothesis, you’ll build models and then test them on holdout sets.
The chapters on R-programming cover the foundational concepts with a focus on modern data science applications. We give you time-saving coding tips and ways of checking your answers within RStudio.
All of the statistical theory is explained, from linear regression to gradient boosted trees, and examples are provided of each model that you can reproduce. Following the course materials “An Introduction to Statistical Learning“, we discuss model training, validation, as well as the advantages and disadvantages to each algorithm.
