[Weights in Horvitz-Thompson statistic for complex samples].
The problem of using ordinary statistical methods basically for simple random samples in analyzing data from complex surveys for non-simple random samples was discussed. Horvitz-Thompson statistic and the poststratification weights were introduced. Illustrative examples were given to show the validity and superiority of Horvitz-Thompson statistic in comparison with statistic used for simple random samples.
