Identify the most important predictive variables in a model
Quantify qualitative variables and incorporate them in a predictive model
Build predictive models to anticipate trends and demand
Syllabus: Regression and Time Series Analysis
This course is designed for students who have taken Data Society’s Introduction to R and Visualization course or have a good knowledge of R programming. This 3 ½ hour course teaches students how to apply advanced regression and time series models to accurately predict business trends and demand.
By the end of this course, students will be able to:
1. Identify the most important predictive variables in a model
2. Quantify qualitative variables and incorporate them in a predictive model
3. Build predictive models to anticipate trends and demand
- Concept reviews: these are comprised of short five question quizzes that cover the most important concepts and ideas in each lesson. They encourage holistic understanding and are multi-faceted ques=on types (i.e. drag and drop, fill-in-the-blanks, matching, etc).
- Exercises: these are additional videos that cover the coding functions in the instructional video in more depth. They are project-based and include coding templates for students to strengthen their skills outside of the course.
- Accompanying PDFs to use as reference materials
- R code templates from the instructional videos and exercises
- Data sets used in the instructional videos and exercises
