For inference regarding relative potency in dilution assays with possible latent effects, a robust procedure is proposed. Monte Carlo studies show that this procedure compares favourably with h o r n procedures. The theory is illustrated by an application to the tolerances of c a b for tinctures of

Abstract
Regression coefficients are regarded as stochastic variables in order to account for this kind of variability. This is needed, because differences in responses at successive doses vary generally and thus the assumption of constancy of regression coefficients is violated.

This paper proposes a method for using multi-auxiliary information at both the design and the estimation stages of a sample survey. The proposed method is an extension of the clessical multivariate method of OLKIN (1968). The resulte of AQARWAL and KUMAR (1978) come out aa a special case.
We propose a logistic regression analysis of unmatched or frequency matched case-control studies with conditional maximum likelihood estimation through post hoc stratification. In this model fewer parameters have to be estimated. With a simulation study we show that parameter estimates have smaller
## Abstract A ratio type estimator using two auxiliary variates has been proposed and conditions are obtained to choose between proposed estimator and OLKIN'S (1958) estimator using two auxiliary variates.
## Background: The ratio of two measured fluorescence signals (called x and y) is used in different applications in fluorescence microscopy. Multiple instances of both signals can be combined in different ways to construct different ratio estimators. Methods: The mean and variance of three estimato
