AbstractThis paper discusses analysis of dispersion tests in tables with spoiled data, that is, where some cells are missing. BENNETT(1987) gave a method for estimating the missing cells in a two‐way table and illustrated it with a simple example. This paper uses GLIMto estimate the models and indicates that the General Linear Model performs the computations without need to estimate the missing values. The binomial error model also may be used for this problem, and is the more natural approach to the proble
