Consider the two-dimensional discrete random
vector Q with PF
[3.25]
Calculate
.
Solution
[s1]
Accordingly, we should first calculate
and
.
This will enable us to calculate
and
.
Then we can calculate
.
From [3.25], we determine the marginal PFs:
[s2]
and
[s3]
From these and definitions [3.3] and [3.7], we calculate:
