trendingBot

NEW IDEAS
any situation = multiple behaviours
any behaviour = mathematically describable
error in predictions = wrong variable selection
user intervention = wrong model delimitation
_________
trad. statistics
lots of user-defined parameters
lots of simplifications
lots of assumptions
complex methods
not to-the-point solutions
"cannot" has no meaning
doe
same as statistics
max/min = too simplified
determine how measurements have to be performed
