Re: Calculating with imprecise values

Hello there,


I've used so called 'sensitivity' analysis in the past to measure changes
in functions with respect to a given variable and this helped understand
things better sometimes especially when human error is involved.

For example....

for the equation with some function F:
  y=F(a,b,c)

the sensitivity with change of parameter 'a' might be 100 times as great
as with parameter 'b', and perhaps the sensitivity with respect to 'c'
might be 1000 times lower than with 'a', meaning y hardly changes
with 'b' or 'c' but changes quite a bit with parameter 'a'.  Thus,
the error in measurement in 'b' or 'c' doesnt matter as much as with
the error in 'a'.  This would mean great care should be used in measuring
'a' while with 'b' or 'c' you might get away with estimating from other
parameters or whatever.


Take care,
Al

And, good luck with your Euphoria programming!
