I have completed the following mathematically inclined courses offered at LSE:
1) Mathematical Methods (Which includes Linear Algebra and Multivariable Calculus)
2) Elementary Statistical Theory
3) Principle of Econometrics
I am planning to apply for a Phd program to universities in the United States and I've read on some forums that taking challenging math courses might improve one's chances of getting in highly selective schools. So I was wondering if these courses along with usual Econ courses demonstrate would enough rigour to the admissions committee. I am asking this because I have a chance to specialize in Econometrics and Mathematical Economics in my final year and so if I'm missing some math courses, I might be able to cover them up by choosing this specialisation.
