Worth Weighting? How to Think About and Use Sample Weights in Survey Experiments
The popularity of online surveys has increased the prominence of sampling weights in claims of representativeness. Yet, much uncertainty remains regarding how these weights should be employed in analysis of survey experiments: Should they be used or ignored? If they are used, which estimators are preferred? We offer practical advice, rooted in the NeymanRubin model, for researchers producing an...
متن کاملWorth Weighting? How to Think About and Use Weights in Survey Experiments
The popularity of online surveys has increased the prominence of using weights that capture units’ probabilities of inclusion for claims of representativeness. Yet, much uncertainty remains regarding how these weights should be employed in analysis of survey experiments: Should they be used or ignored? If they are used, which estimators are preferred?

متن کاملEntropy and approximation numbers of embeddings of function spaces with Muckenhoupt weights, II. General weights.∗
We study compact embeddings for weighted spaces of Besov and TriebelLizorkin type where the weights belong to Muckenhoupt Ap classes. We focus our attention on the influence of singular points of the weights on the compactness of the embeddings as well as on the asymptotic behaviour of their entropy and approximation numbers.
متن کاملDavenport constant with weights and some related questions, II
Let n ∈ N and let A ⊆ Z/nZ be such that A does not contain 0 and it is non–empty. Generalizing a well known constant, EA(n) is defined to be the least t ∈ N such that for all sequences (x1, . . . , xt) ∈ Z, there exist indices j1, . . . , jn ∈ N, 1 ≤ j1 < · · · < jn ≤ t, and (θ1, · · · ,θn) ∈ A with ∑n i=1 θixji ≡ 0 (mod n). Similarly, for any such set A, we define the Davenport Constant of Z/n...
متن کاملIntegral Representation with Weights Ii, Division and Interpolation
Let f be a r × m-matrix of holomorphic functions that is generically surjective. We provide explicit integral representation of holomorphic ψ such that φ = fψ, provided that φ is holomorphic and annihilates a certain residue current with support on the set where f is not surjective. We also consider formulas for interpolation. As applications we obtain generalizations of various results previou...
