Uncertainty Maximin Criterion –Determine worst possible outcome for each strategy –Select the strategy that yields the best of the worst outcomes PowerPoint Slides Prepared by Robert F. Brooker, Ph.D. Copyright ©2004 by South-Western, a division of Thomson Learning. All rights reserved.

Uncertainty: Maximin The payoff matrix below shows the payoffs from two states of nature and two strategies. PowerPoint Slides Prepared by Robert F. Brooker, Ph.D. Copyright ©2004 by South-Western, a division of Thomson Learning. All rights reserved.

Uncertainty: Maximin The payoff matrix below shows the payoffs from two states of nature and two strategies. For the strategy “Invest” the worst outcome is a loss of 10,000. For the strategy “Do Not Invest” the worst outcome is 0. The maximin strategy is the best of the two worst outcomes - Do Not Invest. PowerPoint Slides Prepared by Robert F.

Uncertainty: Minimax Regret The regret matrix represents the difference between the a given strategy and the payoff of the best strategy under the same state of nature.
