Confidence and prediction intervals explained... (with a Shiny app!)

This semester I started teaching introduction to statistics and data analysis with R, at Tel-Aviv university. I put in a lot of efforts into bringing practical challenges, examples from real life, and a lot of demonstrations of statistical theory with R.


I have taught and/or scheduled to teach the following courses:

  • Introduction to Data Science with R (in collaboration with Naya Collegue), ongoing public course (you can register at Naya and join it).
  • R corporate training course (tidyverse and business applications, statistical learning theory and practice). These are licensed as CC BY-NC-SA 4.0, you are free to share and adapt, just provide proper attribution.
  • Introduction to statistics and data analysis with R (Tel Aviv University, scheduled A, B 2019-2020, semester B 2021).
