Definition
Each term in the weighted least squares
criterion includes an additional weight, that

CHOICE OF A PRIOR DENSITY
In Example 4, the prior distributions of
p1 and p2 were given for 17 different
values.
Note that 0 p1, p2 1 and that there are
infinitely many possible values between
0 and 1.
When practically possible, we give prior
