Thanks for the reply, Yuri. Could you please check this definition for me in those books, because I simply don't have them. I agree, that life may make some corrections in math functions :)

Besides, Andrew quoted the book of Theory of Probabilities... It's not the same, as Financial Statistics, I believe...
