Causal Inference – The Mixtape

Book is riddled with mistakes which makes you lose confidence to go further. I spent almost 2 hours trying to understand a simple set theory which didnt make sense at all with what is written. Finally, I gave up and checked the online version of this book and realized it is a mistake in the printed version! (Images attached)Given that this book was written in 2021, It is fair to expect that basic simple mistakes would have been corrected already. Given that I am a novice in causal inference, how do I recognize further mistakes in the material that might go unnoticed. If I have to double check every concept in the online version of the book, it completely defeats the purpose of owning a hard copy in the first place.Disappointed that I have spent 2500 bucks on this.Please stick to online version, it looks like hardcopies havent been upgraded since 2021.
