Probabilities for Joint Events (Command Program)

Probabilities for Joint Events (Command Program)

To display the joint probability of two or more chance events, list the events in a single command. The event names must be separated by a comma.

Competition,MarketShare;

Because the states of the events in this command are not specified, the Session Log displays the joint probability of events B and D over all the states.

Competition,MarketShare
__Competition.Strong
___MarketShare.Gain: 0.16
___MarketShare.Lose: 0.64

__Competition.Weak
___MarketShare.Gain: 0.14
___MarketShare.Lose: 0.06

A joint probability is the probability of two or more events all occurring. For example, the probability that Competition is Strong and that MarketShare is Gain is 0.16. The following formulas display how those probabilities are computed.

__Competition.Strong
___MarketShare.Gain
Competition.Strong*(MarketShare.Gain | Competition.Strong)
___MarketShare.Lose
Competition.Strong*(MarketShare.Lose | Competition.Strong)

__Competition.Weak
___MarketShare.Gain
Competition.Weak*(MarketShare.Gain | Competition.Weak)
___MarketShare.Lose
Competition.Weak*(MarketShare.Lose | Competition.Weak)
