Hey,
I know how to find the expected value from the density function when it is in the form:
(example)
| y^2 -1<y<1
|
fy =|
| 0 elsewhere
Ey = integral(upper limit 1, lower limit -1)[y*y^2 dy)
but, what if the density function looks like this:
| y^2 -1<y<0
|
fy =| y^2 - y 0<y<1
|
| 0 elsewhere
how do you approach here?
