Calculus for Statistics If one were to learn calculus solely for the purpose of learning statistics, what should he focus on? If this is a ridiculous question and the honest answer is “All of it,” that is of course an acceptable answer. But if not, what aspects of calculus are particularly salient for learning statistics? Can certain parts be skipped over or should certain parts be emphasized? Welcoming input from anyone conversant in both advanced calculus and advanced statistics. Thanks in advance!

Learn how to differentiate and integrate, and what each of these concepts mean when applied to multi variate functions. I mean Riemann integrals. This alone will get you a long way in statistics. It’s like knowing how to ride a bus and subway in the city. You can get anywhere within the city limits.
I’m assuming you don’t include the probability theory in your ask, because that is a whole different level of mathematics. This would be like having a 4x4 car, so you get to venture outside your town on your own.
