Question:
3.11 ( ) We have seen that, as the size of a data set increases, the uncertainty associated with the posterior distribution over model parameters decreases. Make use of the matrix identity (Appendix C)
M+ vvT−1 = M−1 −
(M−1v)
vTM−1 1 + vTM−1v
(3.110)
to show that the uncertainty σ2N
(x) associated with the linear regression function given by (3.59) satisfies
σ2N
+1(x) σ2N
(x). (3.111)
