    Honestly this 5 minute video covered a week's worth of curriculum so well, goes to show how inefficient the education system can be

    These videos are excellent! I have never had to use excel or perform anything resembling these operations in my life. Suddenly I find myself in a graduate class in which the professor expects us to all be proficient in this topic going in. Gulp! I met with the professor and still nothing has made sense the way these videos do. Thank you for saving my grade, sanity, and scholarship!!!

    Suppose under minimax and optimistic we found 24,23,23 how do we choose our min regret . I know books said we add an additional factor but to were exactly ?

    • @joshemman
      @joshemman  6 месяцев назад

      If you're provided additional factors, then apply them to the alternatives to determine the better one. Typically, if there is a tie between your best options, say A and B, then you are indifferent between them.

    what is "equally likely criterion" in these case?
    is this the "minimax regret"?

      @joshemman  3 года назад

      No, "equally likely" is not "minimax regret". For "equally likely", choose the decision with the minimum average.

    hey sir, just wanted to clarify one doubt - could you please tell why did you take -9 for s3 of minimax regret approach instead of -5? when that is the lowest value as we are doing costs.
