This IBM 7090-94 program was designed to analyze paired comparison data with or without an absolute judgment set of data. The maximum number of stimuli is equal to 70 the maximum subjects in one study is 99999. This program computes the frequency matrix KFREQ, the matrix of proportions P, the normal transform HN, the arcsin transform HA-ARCSIN2P-1, the logistic transform HLLOGP1-P, the scale values for all 3 transforms, estimates of the arcsin from the normal and logistic scale values, and an analysis of variance and reliabilities for the estimates. The main part of the questionnaire consists of the pairs of objects to be judged by the subject, who is asked to put a cross next to the object of the pair which is preferred or favored in reference to some designated characteristic. Following this main section there may follow an absolute judgment Like-Dislike section of the questionnaire which consists of the list of K objects. The subject is asked to check each object as to whether he likes favors or dislikes does not favor the object when considered in reference to the same designated characteristic. A checking program is included with an output identifying certain types of errors. There are about 7939 decimal words not used in the program.
