Jean-Yves Jaffray

Jean-Yves Jaffray (1939–2009) was a French mathematician and economist who made influential contributions in the fields of decision theory and mathematical statistics.[1][2] He pioneered methods in decision theory such as linear utility theory for belief functions,[3][4] bridging the gap between expected utility and the maximin rule by using subjective probability to encompass belief functions.[1]
