A class of regression type estimators using the auxiliary information on population mean and population coefficient of variation is proposed under stratified random sampling. The expressions of its bias and mean square error under are obtained Further the expression of minimum mean square error under the optimum value of the characterizing scalar is also given in this section. An optimum allocation with the proposed class is obtained and its efficiency is compared with that of Neyman optimum allocation.
