Hi all,
I'm doing the exam-style question in CT6 Chapter 1 (Decision Theory) and am wondering if there are any mistakes in the solutions.
It's the question where we're given the loss function
O1 O2 O3
D1 23 34 16
D2 30 19 18
D3 23 27 20
D4 32 19 19
----
For part (i), state which decision can be discounted immediately. I came up with 2 answers, D2 or O3, because D4 dominates D2 (losses are larger) or O2 dominates O3 (gains are larger).
yet the solns only say D2?
----
Secondly, part (ii) "determine the minimax solution to the problem" - doesn't say whether it's for player A, player B, or *both* player A and B. Does that make sense? The minimax solution is presented as being D3, but that's only a decision that player B can make.
Would appreciate any light that can be shed on this! Thanks in advance!
Also... if anyone is looking for a CT6 buddy to bounce ideas off, PM me! I need more motivation....
