Later, the geneticist S. Wright (1923–1934) and the philosopher and computer scientist J. Pearl (1986–1987) developed the tools, but their notation is too complicated to formulate the mathematical background. Here we mainly follow the up-to-date discussion of statisticians S. Lauritzen and N. Wermuth, and try to juxtapose the directed–undirected and discrete–continuous cases.Marianna BollaFatma AbdelkhalekMáté Baranyi
