Thanks for all the lectures and notes etc. As always really helpful seeing the stages of worked examples rather than just the finished result as you get in a study text.
It says ‘coming soon’ for chapter 22, big data. Is it likely before the March 23 sitting?
However, there are no calculations involved for this chapter and so everything needed can be gained by just reading the notes (and then asking in this forum if you are not clear about anything) 🙂
