comment Is it possible that we can use “+” to add two vectors in polar form?
You can use Module[] to encapsulate your procedure…

You might want to see this.

comment Switching ArcTan argument from a sequence to a list
The behavior of ArcTan[0, 0] may or may not be desired, in which case there is the alternative Arg[x + I y].

comment Finding skewness and kurtosis numerically in Mathematica
Another possibility would be to just define a function for the moments, and then assemble the expressions for variance, skewness, and kurtosis in terms of those moments. Tho, this may or may not be more numerically stable, so some testing would be needed.

comment Multiple lines in an If statement
The indentation is fine; the braces, not so much.

Any special structure (e.g. symmetry, sparseness) in your matrices?

comment How I can integrate $\int_0^{a} x e^{-\frac{b^2 x^2}{2 c}} J_0(n x) dx$?
Ah, Laguerre; that one could actually be useful numerically; sometimes those series have quicker convergence than Taylor series.

comment OLS Estimation - Computational results vs. calculation by hand
At the very least, you have DesignMatrix[], PseudoInverse[], and LeastSquares[] for reference.
