Singh, Garib Nath; Upadhyaya, Lakshmi Narayan A class of modified chain-type estimators using two auxiliary variables in two phase sampling. (English) Zbl 0859.62017 Metron 53, No. 3-4, 117-125 (1995). Summary: We proposed a class of modified chain-type estimators by making use of a known coefficient of variation of a second auxiliary character in two-phase sampling. It has been compared with various estimators including those derived from the proposed one. The performance has been supported by a numerical example.
