“…Sometimes, information on auxiliary variable is not available for all the units of population, for such situation two-phase (double) sampling is a cost effective methodology for generating the valid estimates of unknown population parameters of auxiliary variable in first phase sample. Some of the novel works in two-phase (double) sampling may be referred as Chand [2], Kiregyera [4] [5], Mukharjee et al [7], Srivastava et al [26], Singh and Singh [23], Singh et al [24], Singh and Upadhyaya [15], Upadhyaya and Singh [27], Singh [13], Pradhan [8], Bandyopadhyay and Singh [1] and Singh and Sharma [16] [17] among others. In sample surveys due to various reasons often it is not possible to collect the desired information from all the units selected in the sample.…”
