STAT/BIOSTAT/CSSS: 529 SAMPLE SURVEY TECHNIQUES - SPRING 2015

STAT/BIOSTAT/CSSS: 529 SAMPLE SURVEY TECHNIQUES

Jon Wakefield
Departments of Statistics and Biostatistics

This class concerns the analysis of data collected via surveys. Such data require specialized methods for analysis, to account for the non-random sampling that is often carried out for logistic or efficiency reasons. Ignoring the design can lead to estimators with substantial bias and inappropriate variance estimates.

Complex survey designs are now commonplace in many disciplines, including the health sciences, global health and demography. Examples from the lecturers own research will be discussed, including the estimation of health indicators (e.g., smoking, diabetes) across health reporting areas in King County using BRFSS survey data, and estimation of under 5 child mortality across regions of Tanzania using DHS and HDSS data.

In this course, modern estimation techniques will be described along with practical implementation using the R computing environment, and specifically the survey package.

A variety of complex designs will be discussed including: simple random random sampling, stratified random sampling, probability proportional to size sampling, cluster sampling, and multistage sampling.

Design-based, model-based and model-assisted methods of estimation will be described and critiqued.

Students will also learn how to unravel the mysteries of the construction and use of design weights.
So if you think you might have a weight problem, this is the course for you.
Post-stratification and raking will also be described.

The class will meet on Tuesdays and Thursdays, 10.30-11.50 in LOW 105.
