It is shown in this note that for testing linear hypotheses in categorical data Wald's statistic  is equivalent (i.e., algebraically identical) to the χ21 statistic of Neyman , and for testing nonlinear hypotheses it is equivalent to the χ21 statistic using Neyman's linearization technique, whenever these χ21 statistics are defined.
