Answer:
σˆ =
sPn
i=1 X2
i
2n
Step-by-step explanation:
To obtain, the maximum likelihood ratio, we use the following method.
l(σ) = Xn
i=1 "
− log 2 − log σ −
|Xi
|
σ
#
Let the derivative with respect to θ be zero:
l
0
(σ) = Xn
i=1 "
−
1
σ
+
|Xi

σ

#

n
σ
+
Pn
i=1 |Xi
|
σ
2
= 0
and this gives us the MLE for σ as
σˆ =
Pn
i=1 |Xi
|
n
Again this is different from the method of moment estimation which is
σˆ =
sPn
i=1 X2
i
2n
As our answer
Answer:
Step-by-step explanation:
there are 8 numbers
we want one of them (number 4)
which is 1 in 8
that is:
The height is 5 meters :)
Answer:
