Abstract:

A PPS purposive selection and estimation was studied. A purposive sampling proposed by Guarte and Barrios (2006) is used. Instead of SRS, PPS with auxiliary variable was used in the selection. Results were compared to SRS estimates and SRS purposive. Standard error and coefficient of variation of estimates were basis for comparison. It was shown that PPS purposive has comparable results with SRS purposive and both have better performance compared to SRS.
