First message (to me) from Carl-Erik Särndal’s talk
The method of classical probability sampling does not work anymore in governmental social surveys because of increasing nonresponse rates (and diverging patterns of nonresponse)
2
Even a stronger message: Paradigm shift
The paradigm of classical probability sampling is shifting / has shifted in the context of Official statistics
4
Paradigm shiftMore complex strategies have
gradually superseded the strategies relying solely on probability sampling
BUT: Probability sampling still constitutes a component in the new strategies
5
Signs of paradigm shift
Mainstream statistics and survey sampling are more and more interacting and learning from each other
