These four topics are amplified in order in the four paragraphs below. A set of recursion formulas was obtained for enumerating the decision patterns for n means. x_i was given by the equation See: Equation where i = 1, 2,...,n-1. In IV, formulas were derived which express d_j,i+1 as a function of the x_i. This made possible the writing of the bounding equations for any decision region involving n means. The regions (1,2), (1,2,3), (1,2,4), ..., (1,2....,n) for the multiple range tests were described in the sample-space of differences among n means.145 leavesBTDapplication/pdfenIn CopyrightLD5655.V856 1955.W563Multiple comparisons (Statistics)Dissertationhttp://scholar.lib.vt.edu/theses/available/etd-01122010-020231/
