>>12188708Single studies/papers are nice, but they aren't as valuable as an accumulation of resources (a book)
Probability and Statistics/modeling + CS book in either python or R (the ability to model just about anything in your life is pretty damn valuable, and knowing how to think about data/statistics is really useful in talking over the noise in reported numbers, from politics to the economy). I work in drug prediction/modeling, and I model just about fucking anything if I have numbers (from my weight loss to my finances). I use R since its easy to just graph/model things in a few lines. Also makes you valuable to the market (for example I have a degree in cell biology, it was super easy to get a job in modeling because I already knew how to do it (and despite the meme-shit around here, coding is still extremely valuable; they hired me because I could code, the modeling was just a plus)
You can learn how to code from a project and googling/stack exchanging everything, but after a bit, to REALLY understand code, nothing beats a good reference book.
