Abstract :In this paper we have proposed a general class of estimators intwo phase sampling using multi-auxiliary variables for estimating populationmean of study variable in the presence of non-response for both study andauxiliary variables at second phase. Special cases of suggested class have alsobeen deduced. The expressions of bias and mean square error have also beenderived. Mathematical and empirical comparison has been made for comparingthe efficiency of proposed estimators
