Is there a simple way to get access to the content of the data registers holding the values for statistic calculation? (data you enter with Sigma +)I do not mean the six registers 28 - 32, but the list of values representing the population or sample.

I need to calculate "Sigma x^3" and the default statistic functions only give me "Sigma x^2". Is it possible to program a loop starting at i=1 to i=n where I can read the list content value by value, raising it to 3 and STO+ in a variable representing "Sigma x^3" when the loop-routine reached its end?

I know I could write an input-loop to enter the sample values not making use of "Sigma+" to get around the problem. But I would like to stick to the generic statistic input routine with the "Sigma+" which enables me to do further calculations with the "onboard" statistic functions.
