Modification of Murthy’s estimator using general selection procedure for unequal probability sampling without replacement
Nadeem Shafique Butt, Muhammad Qaiser Shahbaz
A new estimator of population total has been developed following the method of Murthy (1957) by using the Shahbaz and Hanif (2003) General selection procedure. Two special cases have been obtained of the general estimator. Empirical study has been carried out to obtain the most suitable value of the constant involved.
