Empirical Test of Efficiency Comparison Between PPS Estimation and Simple Random Sampling
The theory of sample survey reveals that the efficiency of PPS sampling is superior to simple random sampling. By giving examples of estimation to total amount and mean value of the whole Chinese society's fixed asset investment in the major industries of various regions in 2008, this
paper verifies the efficiency of PPS estimation and simple random sampling under the condition of small samples. The results show that the efficiency of PPS sampling is superior to simple random sampling whether in terms of sampling efficiency and sampling error or interval estimation under
the condition of 95% confidence level.
