EMV(Ai)

Selecciona una de las siguientes respuestas posibles:

  • refers to the expected monetary value of decision alternative, i. There may be many decisions possible. We will let 1 stand for the first decision, 2 for the second, and so on. The lower- case letter i represents the entire set of decisions.

  • refers to the probability of the states of nature. There can be an unlimited number, so we will let j represent this possible outcome.
