Method of graphical analysis of 2 + 2 and 3 + 3 biological assays with graded responses
Barbara Warner · Journal of Pharmacy and Pharmacology · 1964
Abstract Three examples of 2+2 and 3+3 biological assays with graded responses are analysed graphically. The method described has the advantage that only two “general purpose” nomograms are necessary for the analysis of assays with a wide range of ratios of successive doses and numbers of observations; assays with block restrictions may also be analysed. The accuracy of the method is discussed. An appendix gives the theory of the method and of the construction of the nomograms.
