It has been some time since I've been in a statistics course. I actually have a degree in statistics but it has been some time, so I can't recall the upper level stats. I know Elementary Statistics and Statistical Methods but as for theoretical stats I would need some help. As for proofs in stats, would I need to read, intro to proofs, analysis and linear algebra books before proceeding into reading higher level stats. I would really appreciate feedback, I would love to contribute to the mathematics world and I really enjoy statistics.
