Abstract:
|
This paper describes the weighting procedures used for the sample of records from the Guatemalan National Police Archive. The decisions made about sampling procedures to address the structure of the Archive resulted in a number of special problems when calculating the weights. First and foremost, the universe from which samples were selected is highly unusual and fluid, with sparse knowledge of measures of size. At more than one stage of selection, probabilities of selection were not known, requiring weights to be based on estimates of the probabilities of selection. There were difficulties stemming from operational issues, such as the movement of documents while the survey was conducted and empty space within containers.
