CB>In statistics it is recognized that there are uncontrollable factors

CB>factor.  (I did some of these lengthy calculations by hand back in the
CB>70's - now I can't even remember what the process is called.)
CB>Sheila, if you're reading this, do you remember any of the math
CB>processes involved in this?  My memory is shot.
I have not done that type of statistical coursework. Much of mine has
been either (1) at the introductory level, or else (2) at the
theoretical level.
