A Computer Program for the Method of Successive Intervals

range 2~~~ to Vi. The result of applying the method of successive intervals is therefore a matrix of frequencies {x~~} where ~~, is the number of times that stimulus Sj was placed into category Ii. On the basis of such data this program will calculate maximum likelihood estimates of the ~~ values (i = 1, 2, ’’’ ~ ― 1) and JLJ and (jj values where ,~, is the mean and cr, is the standard deviation of the perceived distribution of S,. The first stimulus, 81, is taken as a
