Poisson_games
In game theory and political science, Poisson-game models of voting are used to model the strategic behavior of voters with imperfect information about each others' behavior.[1] Poisson games are most often used to model strategic voting in large electorates with secret and simultaneous voting.
A Poisson game consists of a random population of players of various types, the size of which follow a Poisson distribution. This can occur when voters are not sure what the relative turnout of each party will be, or when they have imperfect polling information. For example, a model of the 1992 United States presidential election might include 4 types of voters: Democrats, Republicans, and two classes of Reform voters (those with second preferences of either Bill Clinton or George H.W. Bush).
