Deady knows a lot more about these types of numbers than I do. My advanced training background is largely cryptography. The second you assume knowledgeable people can't teach you anything, you've failed yourself.
That shit is over my head, same way the Schrödinger equations are the reason I eventually ended up in economics rather than physics.
I have an examined field in econometrics, but truth is I brute forced my way through it (memorized a lot of equations), I don't have an intuitive feel for statistics - did it more to get a feel for the intuition when I read applied economic and social science articles - "a man has to know his limitations." It has served me well over the decades, I'm not intimidated by applied research, whether economics or medicine b/c I have basic understanding of modeling, sampling and inference (and a lot of articles on my hard drive on how to cheat with statistics, know thy enemy!)
It's weird how higher maths work, no problem with Calculus and Calculus II, taught myself Dynamic Programming in graduate school, Set Theory (first chapter of Debreu's
Theory of Value). But advanced undergraduate Probability and Statistics was really hard for me. The same brain that was comfortable with n-dimensional hyperplanes intersecting with convex functions couldn't deal with the basics in those areas.
Now I'm too old for higher maths, so I write policy history.
You lose your analytical sharpness as you age (I was brilliant at 21 on coffee and cigarettes), but gain wisdom and perspective (one would hope).
