STAT6115 Additional Survey Sampling and Estimation

Module Overview

This module will focus on the Design-based, model assisted and model-based approaches to inference; general approaches to weighted estimation; post-stratification, ratio estimation, regression estimation; general approaches to variance estimation; and compensating for non-response.

Aims and Objectives

Module Aims

To introduce students to a range of estimation methods for use in surveys. The main part of the module covers design-based approaches including ratio, regression and other calibration estimators, and how these weighting approaches may be used to compensate for nonresponse. There will also be an overview of methods for variance estimation. The module will provide students with the skills to use imputation to compensate for nonresponse in appropriate situations.

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

  • choose and implement the appropriate method for estimating from surveys, including understanding the properties of different types of estimator.
  • choose an appropriate method to compensate for nonresponse in a survey or missing data more generally. Weighting and imputation approaches will be described.
  • choose and implement an appropriate procedure for estimating the variance of a probability sample.
  • describe the properties of model-based estimators, and deduce estimators from the their model specifications.


• HT, ratio and regression estimation; weights • calibration estimators • model-based estimation • variance estimation – analytical and numerical approaches • weighting for nonresponse • imputation for nonresponse

Special Features

This module is run as a week-long short course, a component of the MSc in Official Statistics

Learning and Teaching

Teaching and learning methods

A variety of methods will be used including lectures and workshops/tutorials, mixed in a 5 day course designed for students on release from the workplace. Students are also expected to read wider than the lecture material as part of their individual study, and to critically appraise different approaches.

Costs associated with this module

Students are responsible for meeting the cost of essential textbooks, and of producing such essays, assignments, laboratory reports and dissertations as are required to fulfil the academic requirements for each programme of study.

In addition to this, students registered for this module typically also have to pay for:

Approved Calculators

Candidates may use calculators in the examination room only as specified by the University and as permitted by the rubric of individual examination papers. The University approved model is Casio FX-570 This may be purchased from any source and no longer needs to carry the University logo.


You will be expected to provide your own day-to-day stationery items, e.g. pens, pencils, notebooks, etc.


Where a module specifies core texts these should generally be available on the reserve list in the library. However due to demand, students may prefer to buy their own copies. These can be purchased from any source. Some modules suggest reading texts as optional background reading. The library may hold copies of such texts, or alternatively you may wish to purchase your own copies. Although not essential reading, you may benefit from the additional reading materials for the module.

Please also ensure you read the section on additional costs in the University’s Fees, Charges and Expenses Regulations in the University Calendar available at
