A general point and interval estimator of the log relative potency is exhibited in closed form, which incorporates prior information on the log relative potency for symmetrical as well as asymmetrical parallel line bioassay. The point estimator turns out to be a weighted average of the usual estimator and the prior mean where the weights are determined by the prior variance.
Classical multivariate regression techniques can lead to an asymptotically efficient restricted estimator of the regression matrix if there is evidence that the regression matrix is of reduced rank. A sublethal joint toxicity experiment involving two agents is used to illustrate this approach.
This paper exhibits a closed-form point and interval estimator of the log relative potency that incorporates prior information on the log relative potency in a symmetric parallel line bioassay. The point estimator turns out to be a weighted average of the usual estimator and the prior mean where the weights are determined by the prior variance.
