Like most methodologists, the authors see surveys and the publications of their results as a process where estimation is the key tool to achieve the final goal of an accurate statistical output. ...
Randomness and sampling exists to support this goal, and early on it was clear to us that the incoming it-is-what-it-is data sources were not randomly selected. ...
The key issue is defining our target population and identifying an estimation strategy that adjusts for the known biases in the source data. ...
