regret = u(possible action) - u(action taken)

Clearly we are interested in cases where the payoff of 'possible action' outperforms the payoff of the 'action taken', so we consider positive regrets and ignore zero and negative regrets.

Maximum regret is the metric that indicates, if you choose an option, at maximum how much you can regret by not selecting other options. It is also known as opportunity cost.

What is the minimum regret method?

The minimax regret strategy is the one that minimises the maximum regret. It is useful for a risk-neutral decision maker. Essentially, this is the technique for a 'sore loser' who does not wish to make the wrong decision.

What is the minimum regret approach?

The minimax regret approach is to minimize the worst-case regret, originally presented by Leonard Savage in 1951. The aim of this is to perform as closely as possible to the optimal course.

What is the savage criterion of regret?

The savage criterion is based on the concept of regret (or opportunity loss) and calls for selecting the course of action that minimises the maximum regret. This criterion is assume that decision maker feels regret after adopting a wrong course of action (alternative) resulting in an opportunity loss of pay off.

What does psychology say about regret?

Regret, like all emotions, has a function for survival. It is our brain's way of telling us to take another look at our choices—a signal that our actions may be leading to negative consequences.

What is Maximin regret criterion?

Minimax regret criterion:

Under the Minimax Regret Criterion Theory, decision-makers attempt to minimize the worst case regret. Regret is defined as the value of opportunity lost. For a set of alternatives, the decision maker calculates the regret and then selects the alternative that has the lowest maximum regret.

What is toxic regret?
