摘要：
A simple procedure for consideration of specified treatment contrasts or sets of contrasts in a paired comparisons experiment is developed. General likelihood estimation and likelihood ratio tests are given. Specified treatment comparisons as appropriate in a particular experiment may be made. The procedure may be used for consideration of factor effects and interactions when the treatments in paired comparisons are factorial treatment combinations. An example is given of a [human] taste preference experiment on coffee with factors, brew strength, roast color and brand, each at 2 levels. Results are summarized in an analysis of chi-squared table very analogous to the typical analysis of variance summary.
