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?

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.

comment problem on strong law of large numbers
Excellent. So we apply SLLN on the denominator and CLT on the numerator.

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.

comment distribution of iid sequence of integrable random variables
Yes, it uses conditional expectation and independence. Its not too difficult after all.

comment application of strong vs weak law of large numbers
Can you give an example where weak law holds but strong law does not hold?
