Applied Survey Data
Analysis is the product born of many years of teaching applied
survey data analysis classes and practical experience analyzing survey data.
We have taught various versions of this course in the ISR/SRC Summer Institute
Program, as part of University of Michigan/CSCAR, and within the Survey Methodology Program at
University of Michigan and University of Maryland. Our goal has been to
integrate teaching materials and practical analysis knowledge into a textbook
geared to a level accessible for graduate students and working analysts who
may have varying levels of statistical and analytic expertise. We
intend to update the materials on this website as statistical and
software improvements emerge with the goal of assisting analyst and researchers
performing survey data analysis.

Stata Review of ASDA
2. Review posted
5.0 out of 5 stars Simply a Great Book,
December 25, 2010 By Dennis Hanseman (Cincinnati, OH United States)
"Applied Survey Data Analysis (ASDA) is a
crystal-clear survey of modern techniques for analyzing complex survey
data. Note the word "analyzing".
This is not a text on sampling methods per
se. Rather, it is a guide to using existing data sets that result from a
complex survey design that employs weighting, clustering, and
stratification. The authors demonstrate how a correct analysis should be
undertaken. In doing so, they review descriptive statistics, categorical
methods, regression analysis (linear and logistic), survival analysis,
and multiple imputation. Most examples use Stata, but some are in SAS.
The level of mathematical sophistication is
not high, although "theory boxes" are interspersed to add additional
detail. Anyone who is challenged by the mathematical level of this book
probably should not be working with survey data in the first place.
In sum, this is an important -- and very
well written -- contribution to the literature on survey data analysis."

5.0 out of 5 stars: "A must-have for anyone analyzing survey data",
(Kristen Olson, Lincoln NE): May 2, 2011.
This review is from:
Applied Survey Data Analysis (Chapman & Hall/CRC Statistics in the
Social and Behavioral Sciences) (Hardcover)
"This book is unique in the extensive
market of books on analysis of survey data. Most data collected on
finite populations are selected with unequal probabilities of selection,
strata and clusters, but most regression textbooks assume a simple
random sample. This is the first full-length textbook that deals with
subclass analyses, categorical data analysis, and various generalized
linear models (from linear regression through hierarchical models) and
complex survey designs at a statistical level accessible to most
graduate students or data analysts. Weight creation and multiple
imputation are also covered.
Readers will not be scared off by 'too many' formulas in this book.
Although formulas are used throughout the book, there is not a great
deal of detailed statistical theory presented; additionally, the 'Theory
Boxes' provide enough information for more statistically inclined
readers to know where to turn for more information. The book is best
used for a more advanced statistical models class, after students have
taken their basic regression/correlation class (and possibly after a
categorical data class). The homework assignments at the end of each
chapter are a useful addition to the text, with the required data sets
available on the book's website. I find that the homework assignments
are best supplemented with additional examples with other data sets,
especially for classes taught repeatedly, but they are a great starting
I strongly recommend this book to anyone wanting a 'how to' book for
conducting and interpreting analyses on complex survey data,
supplemented with extensive documentation on model fitting and
diagnostics under a complex survey design (where they are available). It
is immediately useful, with Stata code for all of the analyses provided
in the text and SAS, Stata, MPlus, R, SUDAAN, WesVar, and SPSS code on

5.0 out of 5 stars: from Sophia
this book in preparation for analyzing NHANES data for the first time.
To give an idea of my background: My formal biostatistics training is
quite limited to what I got through experience on different research
projects and through medical school. I use Stata 12 in a very basic way,
and this was the first project using a large dataset that I did my own
analysis for from start to finish. I've worked with weighted survey data
before, but another statistician was doing all the actual coding.
I thought this book was pretty balanced between theory and practical
issues. A lot of the theory was over my head, but certain parts were
extremely illuminating and useful to read through. They do specify at
least two semester of graduate level statistics or something like that
as a prerequisite, but obviously I don't have that and I still found the
book useful. The real value of the book lies in its numerous and
detailed examples. The authors actually use NHANES data (and other
national datasets) to work through their examples. They walk you through
many different types of analyses, include multiple linear regression,
multiple logistic regression, etc. Many of these examples are very
detailed, and they build the whole model step-by-step and explain the
rationale behind each step and decision. The book is extremely well
organized, so that by flipping through the table of contents you can
immediately find the relevant section for what you want to do with the
data, read through the example, and apply the Stata code directly to
your own analysis.
NHANES does have tutorials about how to work through their data;
although I also found those to be useful and essential, I think that
this book is superior because it does give more background about why you
need to run certain types of analyses and tests rather than others.
I can't believe my university library didn't have this book--I think
it's a totally worthwhile purchase for anyone preparing to work with
large national datasets."

book is clearly written and easy to follow, and well equipped with real
data examples and a book web site. The program codes used in the example
are also available, mostly written in Stata. I like the
presentations with real survey examples and, in particular, the unified
four-step approach to the regression analysis in different models.
Anyone working on survey data analysis would find the book very helpful
and instructive. The book website seems to be a good complement, with
additional resources on this book." (Partial review).

Multilevel models (MLM) offer complex survey
data analysts a unique approach to understanding individual and contextual
determinants of public health. However, little summarized guidance exists
with regard to fitting MLM in complex survey data with design weights.
Simulation work suggests that analysts should scale design weights using two
methods and fit the MLM using unweighted and scaled-weighted data. This
article examines the performance of scaled-weighted and unweighted analyses
across a variety of MLM and software programs.

Weighting Steps on Variance Estimation, Journal of Official Statistics, Vol.
20, No. 1, 2004, pp. 1–18.
Multiple weight adjustments are common
in surveys to account for ineligible units on a frame, nonresponse by
some units, and the use of auxiliary data in estimation. A practical
question is whether all of these steps need to be accounted for when
estimating variances. Linearization variance estimators and related
estimators in commercial software packages that use squared residuals
usually account only for the last step in estimation, which is the
incorporation of auxiliary data through poststratification, regression
estimation, or similar methods. Replication variance estimators can
explicitly account for all of the steps in estimation by repeating each
adjustment separately for each replicate subsample. Through simulation,
this article studies the difference in these methods for some specific
sample designs, estimators of totals, and rates of ineligibility and
nonresponse. In the simulations reported here, the linearization
variance estimators are negatively biased and produce confidence
intervals for a population total that cover at less than the nominal
rate, especially at smaller sample sizes. The jackknife replication
estimator generally yields confidence intervals that cover at or above
the nominal rate but do so at the expense of considerably overestimating
empirical mean squared errors. A leverage-adjusted variance estimator,
which is related to the jackknife estimator, has small positive bias and
nearly nominal coverage. The leverage-adjusted estimator is less
computationally burdensome than the jackknife but works well in the
situations studied here where multiple weighting steps are used.

samples, t-distributions are used when performing hypothesis tests and
confidence intervals. Rules-of-thumb are typically used to approximate
of freedom for
the t-distributions. The standard rule is to set the degrees of freedom
the number of
primary sampling units minus the number of strata. We illustrate some
where these rules can be poor. A simple estimate of degrees of freedom
presented that leads to
improved confidence interval coverage.

Influence Diagnostics for Unclustered Survey Data,
Diagnostics for linear regression models have largely been
developed to handle nonsurvey data. The models and the sampling plans
used for finite populations often entail stratification, clustering, and
survey weights. In this article we adapt some influence diagnostics that
have been formulated for ordinary or weighted least squares for use with
unclustered survey data. The statistics considered here include DFBETAS,
DFFITS, and Cook’s D. The differences in the performance of ordinary
least squares and survey-weighted diagnostics are compared in an
empirical study where the values of weights, response variables, and
covariates vary substantially.

When an analyst faces the problem of estimating model parameters to data
from a complex survey, one of the first questions he often asks is
whether or not to use the survey weights. The appropriate question to
ask, however, is whether the survey design information itself is
relevant, and if so, how should it be incorporated in the analysis. The
debate between the design-based and the model-based schools for making
inferences on model parameters can be explained and clarified using a
model-design randomization framework to describe how the observations
for the sampled units have been obtained.

search is an effective and efficient approach when analyzing non-survey
data to detect a group of influential observations which affect
regression estimates greatly if they were removed from the model
fitting. It has the advantages of avoiding masked
the outliers, as well as automatically identifying influential points.
Compared to multiple-case deletion diagnostic statistics, this method
reduces computational burden, especially when the dataset is very large.
In this research we adapted the forward search to linear regression
diagnostics for some types of complex survey data. While keeping the
existing advantages of this method, we incorporate sample weights and
the effects of stratification. A case study is conducted to illustrate
the advantages of the adapted method.

Summary. Longitudinal data from labour force
surveys permit the investigation of income dynamics
at the individual level. However, the data often originate from surveys with
multistage sampling scheme. In addition, the hierarchical structure of the
data that is imposed
by the different stages of the sampling scheme often represents the natural
grouping in the
population. Motivated by how income dynamics differ between the formal and
of the Brazilian economy and the data structure of the Brazilian Labour
Force Survey, we extend
the probability-weighted iterative generalized least squares estimation
method. Our method is
used to fit multivariate multilevel models to the Brazilian Labour Force
Survey data where the
covariance structure between occasions at the individual level is
modelled.We conclude that
there are significant income differentials and that incorporating the
weights in the parameter
estimation has some effect on the estimated coefficients and standard

THE GEORGE WASHINGTON UNIVERSITY, 2013,
Link to Paper
Characteristic (ROC) curve analysis has gained an increased interest in
past decades. It has been widely used to evaluate the performance of
diagnostic tests. The area under the ROC curve (denoted by AUC) is the
most commonly used summary index of a ROC curve. A larger AUC value for
a diagnostic test usually means that the test has better discriminating
ability between diseased and non-diseased populations. Both parametric
and nonparametric methods have been developed to estimate and compare
AUCs. However, these methods are standardly used for simple random
sample, not complex samples.
In surveys, complex sample designs with
cluster sampling are commonly implemented. The Hispanic Health and
Nutrition Examination Survey (HHANES) was conducted to assess the health
and nutritional status the population of Hispanic individuals aged 6
months to 74 years in specific areas in U.S. by using a multistage,
stratified, probability design with complex weight calculation. Analyses
without accounting for weighting and clustering effect that is induced
by the complex survey sampling can be biased. Thus, standard statistical
methods of estimation of AUC for the population and its variance are not
applicable to complex survey data.
In this dissertation, we propose an
extension of the nonparametric method in the estimation of the
population AUC that accounts for sample weighting under differing
complex survey designs. We provide and study the accuracy of a jackknife
method, along with balanced repeated replication (BRR), for variance
estimation of our proposed estimator of AUC. We also discuss informative
sample designs where the selection probabilities are related to the
parameter of interest, so that the standard analyses that ignore the
sample weights can be seriously biased. Finally, our proposed methods
are then applied to the Mexican-American portion of the HHANES to
compare the classification accuracy of three predictors for
overweight/obese using measured BMI as a gold standard.
