Rosenberg's test-factor standardization can be interpreted as a special type of marginal standardization. A frequency table after test-factor standardization is the zero-order table for a three-way table that has been standardized to the two-way margials which would exist for the independent and control variables if these variables were independent of each other in the data. Further continuities are drawn between test-factor standardization and log-linear models of contingency tables in the special case of complete interpretation.
