This course will cover the steps used in weighting sample surveys, including methods for adjusting for nonresponse and using data external to the survey for calibration. Among the techniques discussed are adjustments using estimated response propensities, poststratification, raking, and general regression estimation. Alternative techniques for imputing values for missing items will be discussed. For both weighting and imputation, the capabilities of different statistical software packages will be covered, including R®, Stata®, and SAS®.

This course quite help to get as much reliable data as possible for any survey.
interesting material, well taught, lots of short quizzes to enforce understanding.
This is a higher level course. Good for beginners.
Aside from a little hiccup with one of the quiz questions during week 1, this course was worth my time.
