Decision alternative

As explained in Statistics Every Programmer Needs

A decision alternative is one of the mutually exclusive courses of action available to a decision-maker.

A decision alternative is one mutually exclusive course of action available to a decision-maker. Exactly one alternative is selected, while states of nature determine its resulting payoff. section 10.1.1

Structure alternatives for decision analysis by:

  • Listing every available course of action. section 10.1.1
  • Identifying external states of nature that may affect outcomes. section 10.1.1
  • Recording the payoff for each alternative–state combination in a payoff table. section 10.1.1

Investment alternatives

Possible alternatives include Stock Market, Professional Soccer Club, a 50/50 combination, and Savings Account. Their payoffs vary between strong and weak economies, enabling comparison with the Maximax method.

How Statistics Every Programmer Needs covers it

How deep it goes
Defines alternatives and places them in payoff tables, stopping short of broader decision-theory analysis.
Examples
Uses stock market, soccer club, combined investment, and savings account alternatives under strong or weak economies.
What it assumes
Assumes a decision-maker can identify available actions and distinguish controllable alternatives from external states of nature.
What you can do after
Apply it via pandas by listing alternatives, building a payoff table, and comparing row-wise maximum payoffs.
How it connects
Connects decision alternatives with states of nature, payoffs, payoff tables, and the Maximax method.
