Reflection on modern methods: a note on variance estimation when using inverse probability weighting to handle attrition in cohort studies
Marie-Astrid Metten, Nathalie Costet, J. -F. Viel +1
The inverse probability weighting (IPW) method is used to handle attrition in association analyses derived from cohort studies. It consists in weighting the respondents at a given…
A cautionary note on the Hanurav-Vijayan sampling algorithm
Guillaume Chauvet
We consider the Hanurav-Vijayan sampling design, which is the default method programmed in the SURVEYSELECT procedure of the SAS software. We prove that it is equivalent to the Sun…
Closed-form variance estimators for weighted and stratified dose-response function estimators using generalized propensity score
Valérie Garès, Guillaume Chauvet, David Hajage
Propensity score methods are widely used in observational studies for evaluating marginal treatment effects. The generalized propensity score (GPS) is an extension of the propensit…
Exponential inequalities for sampling designs
Guillaume Chauvet, Mathieu Gerber
In this work we introduce a general approach, based on the mar-tingale representation of a sampling design and Azuma-Hoeffding's inequality , to derive exponential inequalities for…
Properties of Chromy's sampling procedure
Guillaume Chauvet
Chromy (1979) proposed a unequal probability sampling algorithm, which enables to select a sample in one pass of the sampling frame only. This is the default sequential method used…
Large sample properties of the Midzuno sampling scheme with probabilities proportional to size
Guillaume Chauvet
Midzuno sampling enables to estimate ratios unbiasedly. We prove the asymptotic normality for estimators of totals and ratios under Midzuno sampling. We also propose consistent var…
Preserving the distribution function in surveys in case of imputation for zero inflated data
Brigitte Gelein, Guillaume Chauvet
Item non-response in surveys is usually handled by single imputation, whose main objective is to reduce the non-response bias. Imputation methods need to be adapted to the study va…
Inference for two-stage sampling designs with application to a panel for urban policy
Guillaume Chauvet, Audrey-Anne Vallée
Two-stage sampling designs are commonly used for household and health surveys. To produce reliable estimators with assorted confidence intervals, some basic statistical properties…
A comparison of pivotal sampling and unequal probability sampling with replacement
Guillaume Chauvet, Anne Ruiz-Gazen
We prove that any implementation of pivotal sampling is more efficient than multinomial sampling. This property entails the weak consistency of the Horvitz-Thompson estimator and t…
Exact balanced random imputation for sample survey data
Guillaume Chauvet, Wilfried Do Paco
Surveys usually suffer from non-response, which decreases the effective sample size. Item non-response is typically handled by means of some form of random imputation if we wish to…
Coupling methods for multistage sampling
Guillaume Chauvet
Multistage sampling is commonly used for household surveys when there exists no sampling frame, or when the population is scattered over a wide area. Multistage sampling usually in…
Joint imputation procedures for categorical variables
Hélène Chaput, Guillaume Chauvet, David Haziza +2
Marginal imputation, which consists of imputing each item requiring imputation separately, is often used in surveys. This type of imputation procedures leads to asymptotically unbi…
Estimation under cross-classified sampling with application to a childhood survey
Hélène Juillard, Guillaume Chauvet, Anne Ruiz-Gazen
The cross-classified sampling design consists in drawing samples from a two-dimension population, independently in each dimension. Such design is commonly used in consumer price in…
Martingale central-limit theorems for pivotal sampling
Guillaume Chauvet
Ordered pivotal sampling is one of the simplest algorithm to perform without-replacement unequal probability sampling. It has found uses in the context of longitudinal surveys and…
A note on the consistency of the Narain-Horvitz-Thompson estimator
Guillaume Chauvet
For the Narain-Horvitz-Thompson estimator to have usual asymptotic properties such as consistency, some conditions on the sampling design and on the variable of interest are needed…
On a characterization of ordered pivotal sampling
Guillaume Chauvet
When auxiliary information is available at the design stage, samples may be selected by means of balanced sampling. Deville and Tille proposed in 2004 a general algorithm to perfor…
