Hello,
Very often we deal with the situation that although a probability density
functions describe (by their shape) some processes in a reasonable way, the
statistical moments do not exist for them. These moments also have very
clear interpretation. Does anybody of you have some thoughts on this
subject, namely what is the philosophy (or is it any) behind this seemingly
obvious fact. Maybe you can recommend some reading about it?
Any help/info appreciated.
