Hi,
I am two years out of undergrad (Economics major) doing data science work, looking to apply for Stats Ph.D. programs. I am a bit lighter on math courses compared to others given my major, although I have taken the prereqs to apply that I am seeing (Calc, Lin. Alg, Stats/Probability). I was thinking of signing up for a Real Analysis course to buttress my application, taking that in the summer or fall term at a university online. Would that help my application you think, or is it not necessary?
