 Feb13 accepted spectrum and phase of function in frequency domain Feb13 comment spectrum and phase of function in frequency domain Sweet. Do you happen to come across function in R that does this similar to matlab? Feb13 comment spectrum and phase of function in frequency domain reference: en.wikipedia.org/wiki/Fourier_transform Feb13 revised spectrum and phase of function in frequency domain added 96 characters in body Feb13 comment spectrum and phase of function in frequency domain Thanks. But I am using R and I don't think it has these functions. I am looking for mathematical formula for finding magnitude/phase so that I can write my functions.

So we apply SLLN on the denominator and CLT on the numerator. Dec11 accepted problem on strong law of large numbers Dec9 comment problem on strong law of large numbers How do you get this result? Dec9 asked problem on strong law of large numbers Dec9 comment what does this set definition mean defined on independent random variables? It is also interesting to see that if I introduce two additional sets, defined as $A2 = (X2=X3)$ and $A3 = (X3=X1)$, $A1$, $A2$ and $A3$ are pairwise independent but not independent.

Dec9 comment martingale and filtration Yes I did Shai. But need better understanding of filtration in continuous-time martingale Dec9 asked martingale and filtration Dec8 accepted distribution of iid sequence of integrable random variables Dec8 comment distribution of iid sequence of integrable random variables Yes, it uses conditional expectation and independence. Its not too difficult after all. Dec7 asked distribution of iid sequence of integrable random variables Dec7 comment How do I nominate someone? I would like to nominate Qiaochu Yuan and Arturo Magidin
