How to Unsubscribe from the UCLA Statistics Seminars Mailing List

You may be receiving our seminar emails because you are subscribed to our seminars mailing list (or one of our other mailing lists). You can determine which is the case by looking at the subject line of a seminar email. You may unsubscribe from the seminar mailing list by sending an email to sympa@sympa.cts.ucla.edu with “unsubscribe stat_seminars” (without quotation marks) in the subject field and the message body blank. This needs to be done from the address that is subscribed. After sending that email please follow the directions in the email response that you receive. If you are getting our seminar emails because of a subscription to one of our other mailing lists then the word “seminars” in the subject field must have the appropriate replacement.

Statistical Inference with Non-probability Survey Samples

Posted: September 24, 2021 | 0 comments

Changbao Wu, Professor
Statistics and Actuarial Science, University of Waterloo

Abstract:

We provide an overview of recent development of statistical methodologies for analyzing non-probability survey samples. Inferential frameworks, critical assumptions and the required supplementary population information are discussed. Three general approaches to inference, namely, inverse probability weighting, mass imputation, and doubly robust estimation procedures, are presented. Practical issues in dealing with feasibilities of the assumptions and incomplete sampling frames are also discussed.
