Selection Bias and Self-Selection

1987
The problem of selection bias in economic and social statistics arises when a rule other than simple random sampling is used to sample the underlying population that is the object of interest.

Acta Mathematica Academiae Scientiarum Hungaricae, 1982
The concept of selective differentiation was introduced and developed in [4]. Here we present selective differentiation from a different viewpoint or, rather, in a new framework. This framework takes some effort to erect but is profitable in terms of the results obtained. It originates from several very simple observations.
