How Stratified Random Sampling Works, With Examples

Stratified random sampling is a method of sampling that divides a population into smaller groups that form the basis of test samples.

PPS Sequential Sampling

If you specify the option METHOD=PPS_SEQ, PROC SURVEYSELECT uses Chromy's method of sequential random sampling. Refer to Chromy (1979) and Williams and Chromy (1980). Chromy's method selects units ...

Sample multiple channels ‘simultaneously’ with a single ADC

So, what’s the problem sequential sampling? After all, if you’ve got, let us say, four channels that you need to sample at some rate F S, and an ADC that’ll sample fully at 4F S and that can be driven ...
