In early days of fifty-five years of its history, several statisticians contributed to its development, to name a few: H.O. Hirschfeld (Hartley, 1935), R.A. Fisher (1940), E.J. Williams (1952) and H.O. Lancaster (1958). This talk will look at its historical development, common ideas behind a plethora of names, basic formulations, and recent work carried out in Toronto. -------------------- Coffee and tea will be served in the Delury Lounge (SS6006) at 3:30 p.m.
