Surveys are an important source of data in many social, health and environmental sciences. When analyzing datasets that were obtained through surveys, failure to take the design aspects into account can lead to invalid estimation and inference, even when the mode of inference is model-based. We begin by describing some of the issues associated with informativeness in analytic inference, and examine the differences between model-based and design-based modes of interference. We then describe a number of new results and approaches in testing and adjusting for design effects, using a combination of parametric and nonparametric tools.
