¥ Signal =
Measurable response to stimulus
¥ Noise =
Components of measurement that interfere with
detection of signal
¥ Statistical detection theory:
H Understand
relationship between stimulus & signal
H Characterize noise statistically
H Can then
devise methods to distinguish noise-only measurements
from signal+noise measurements, and assess the
methodsÕ reliability
H Methods and
usefulness depend strongly on the assumptions
o Some methods are ÒrobustÓ against
erroneous assumptions, and some are not
