Reply to Owen White

The response of Owen White generally supports the notion of computing objective study outcomes for the purpose of reviewing single-subject research. He suggests, however, that our model is not sensitive to trends and proposes a model for computing percentage of nonoverlapping data based upon consideration of baseline trends. We respond that although such a procedure has theoretical merit, it has little practical utility due to the limited number of observations typically found in single-subject baselines; furthermore, when reliable and substantial baseline trends are found, interpretability of study outcomes is seriously limited.
