whose work in data analysis enabled him to formulate methods of deriving
valid information from small samples. He also concentrated on the developments
and applications of techniques for the analysis of variance. Wilks was born in Little Elm, Texas. He studied architecture at Texas and statistics at Iowa. He spent his career at Princeton, becoming professor 1944. Wilks's investigations of the analysis of variance were devoted especially to multivariate analysis. Two of his most original contributions were the Wilks criterion and his multiple correlation coefficient. The US College Entrance Examination Board, which carries out extensive educational tests, found his assistance invaluable in analysing their results. Seeking also to apply these methods to industrial problems, Wilks did fundamental work in the establishment of the theory of statistical tolerance. |
