WebDesign Weights Design weights are used to compensate for non-proportional stratification. For example, in a population containing 100,000,000 men and 100,000,000 women, if you used quotas or stratification to achieve a sample of 80 men and 20 women, then a design weight is created to take this non-proportional stratification into account.

WebFeb 21, 2024 · Survey weights are common in large-scale government-funded data collections. For example, NHIS and NHANES are two large scale surveys that track the health and well-being of Americans that have survey weights.

That is, the sampling design and survey weights are not used (Pfeffermann, D., 2013). Thus, BHR can be vulnerable to model misspecification, resulting in both bias and large variance (Kish, L. and Frankel, M., 1974; Hansen, M. et al., 1983). Additionally, BHR requires specification of a prior.
