Then let $w_{i}=\bar{\unicode[STIX]{x1D70B}}/\unicode[STIX]{x1D70B}_{i}$ be the weight. These weights $w_{i}$ are relative to a baseline of 1, which eases interpretability due to removing dependence on $n$. A weight of 1 means the unit stands for itself, a weight of 2 means the unit “counts” as 2 units, a weight of 0.5 means units of this ...
This chapter highlights key elements of the data collection process that differ across data sources and published reports. These include the study design, the settings for data collection, the individuals included in the data source, and data collection methodologies.
13 Οκτ 2018 · In addition to an overview of weighting and the general theoretical approaches used to justify the use of weights in estimation, this chapter covers the first three weighting steps–base weights (inverse probability of selection), adjustments for unknown eligibility, and nonresponse adjustments.
Until then, however, the health science research community needs to start discussing ways to improve the reporting of analyses that account for design effects and use of sample weights when disseminating research findings based on complex sample data.
