Read from the book “An introduction to statistical learning” up to page 138. This book is more practical and does not get in details about the mathematics used, but it emphasizes why things are done.
Watched many videos of the channel jbstatistics on YouTube , especially on Simple Linear Regression and ANOVA and it’s really helpful.
At 16-11-2019 I learned a lot about ANOVA trying to apply ANOVA in the Airbnb dataset in R. The assumptions are important and they need to be checked every time we run ANOVA. Also checked some programs in Greece regarding an MSc in Data Analysis and thinking about applying to one of them. The cost for the full time program is approximately 6000e. So better start saving 🙂
