Sampling or adjustment?

“When the nonresponse rate is 91%, any sample is a convenience sample.” (Emphasis original.)

“Remember: just about no sample of humans is really a probability sample or even close to a probability sample, and just about no regression model applied to humans is correct or even close to correct. So we have to worry about sampling, and we have to worry about adjustment.”

Sampling without replacement with specified marginal sampling probabilities

The {sampling} library by Yves Tillé and Alina Matei implements Brewer’s (1975) method – discussed above – as UPbrewer. Tillé’s (2023) review looks interesting too, cataloguing a bunch of incorrect methods and what to use instead.
