The specific methods of PPS sampling are as follows:
1. First, determine the primary sampling unit (PSU), which can be a fixed conventional unit. To determine the PSU, we need to have a specific directory of these primary sampling units, as well as the specific number of the investigated personnel in each primary sampling unit, which can be used to estimate the number of people
2. Determine which primary sampling units to select. If there are few primary sampling units, all of them can be selected. If there are too many primary sampling units, some of them can be selected randomly
3. Select the specific survey objects from the selected primary sampling units. If all the members of the primary sampling units selected in the second step are taken as the survey objects, it is called two-stage cluster sampling. If only the number of people in each sampling unit is determined according to the number of people in the primary sampling units, it is called PPS sampling, Some calculation is needed.
