It has been noted that non-response creates problem mostly in all
types of surveys and this cannot be eliminated by simply increasing
the sample size. Non-response may be non-ignorable or ignorable
which depends whether it is correlated with the target variable or
not Little (1982) and Glynn, Laird and Rubin, (1993)]. Non-response
is caused when surveying human population hesitates to respond in
surveys and this is increased when sensitive issues are discussed
in surveys. It has been observed that non-response increases bias
in estimates which is main reason of reducing efficiency of the
surveys. Many methods have been considered by different survey
statisticians for estimating the population characteristics in the
presence of non-response for two-phase sampling. In this aspect the
sub-sampling method has been a popular one.
