**Titel:** **Order Sampling with Inclusion Probabilities Proportional to Size**

** Sammanfattning: **
One vehicle for utilization of auxiliary information in sample surveys is to
use pps sampling, i.e. to sample (without replacement) with inclusion
probabilities proportional to given size measures. When searching for good
pps schemes, the following aspects are of main interest. The scheme should

- be simple to implement
- lead to good estimation precision
- have nice variance estimation properties.
