Introduction to Fisher (1926) The Arrangement of Field Experiments

摘要: In 1919, the Director of Rothamsted Experimental Station, Sir John Russell, invited Ronald Aylmer Fisher, a young mathematician with interests in evolution and genetics, to join small group scientists at order that [see Russell (1966, p. 327)] “after studying our records he should tell me whether they were suitable for proper statistical examination might be expected yield more information than we had extracted.” Fisher accepted invitation very short time realized (loc. cit.) “that was man great ability; fact genius who must retained.” few years followed, introduced subdivision sums squares now known as an analysis variance (anova) table (1923), derived exact distribution (log the) ratio two independent chi-squared variates (1924), principles blocking randomization. well randomized block, Latin square, split-plot experiments, latter anova tables (1925), promoted factorial foreshadowed notion confounding (1926). Of course made many contributions theoretical statistics over this same period (1922)], but above relate directly design field topic paper follows. It incredibly productive his ideas quickly transforming agricultural experimentation Great Britain widely, major respects these have remained basis day.
