Why We Should Put Some Weight on Weights

Journal article | Zeitschriftenartikel

Weighting is one of the major components in survey sampling. For a given sample survey, to each unit of the selected sample is attached a weight that is used to obtain estimates of population parameters of interest (e.g., means or totals). The weighting process usually involves three steps: (i) obtain the design weights, which account for sample selection; (ii) adjust these weights to compensate for nonresponse; (iii) adjust the weights so that the estimates coincide to some known totals of the population, which is called calibration. Unfortunately, weighting is often considered as a process restricted to survey sampling and for the production of statistics related to finite populations. This should not be the case because, when using survey data, statistical analyses, modeling and index estimation should use weights in their calculation. This paper tries to describe why weights are useful when dealing with survey data. First, some context is given about weighting in sample surveys. Second, we present the use of weights in statistical analysis, and we give the impact of not using the weights through an illustrative example. Third, the above three weighting steps are formally described.
