## Die don’t remember the last roll. Really. [General Sta­tis­tics]

Hi Helmut,
and thank for trying to help.

If it did remember the last roll and the outcome was somehow a function of it, wouldn't that be correlation?

And how is the die and last roll mental image fitting in with Z and s being indepedent? I think it fits better into the mental picture of errors in a model being IID.

Or more generally:
From a sample of size N I am deriving two quantities A and B. Under what cicumstances will A and B be independent? A die with Alzheimer does not really shed light on it, does it?

Kindly help me a little more. I do not see the idea of the R code but it executes nicely except errors for idx.m and idx.v.
Code on this forum rarely provides clarity for me. This has nothing to do with the code, but has everything to do with me

Pass or fail!
