Mathematics of Biological Assay [PDF]
IF in a biological assay the mean responses, y11, y12, of two groups of n animals to doses of a standard preparation the logarithms of which are x11, x12, are compared with the mean responses, y21, y22 to doses of the preparation under test the logarithms of which are x21, x22, it is often possible to express the relationship between dosage and ...

On the calculation of the error of biological assays [PDF]
It is now realized by a number of workers that the formula which it has been customary to use hitherto for calculating the limits of error of the dose corresponding to a given response (e.g. the median effective dose) or of the result of a biological assay is only approximate.
