(a)Consider the hypothesis pair:
H0:Y = N
H1:Y =S + N
Where S and N are independent and identically distributed random variables
-x
having probability density function p(x) = e , x >= x
Find the maximum likelihood decision rule for this hypothesis testing problem
(b)
Now consider the sequence of observations:
H0: Y = N i = 1,2...,n
i i
H1: Y = S + N i = 1,2,...,n
i i
where n is some positive integer and where S and N are independent and
i
identically distributed random variables described as before.
Determine the maximum likelihood decision rule.
要問的是第b小題，有點看不太懂題目
麻煩請高手解答，感謝
