A survey of data partitioning and sampling methods to support big data analysis

open access: yesBig Data Mining and Analytics, 2020
Computer clusters with the shared-nothing architecture are the major computing platforms for big data processing and analysis. In cluster computing, data partitioning and sampling are two fundamental strategies to speed up the computation of big data and

Subsampling MCMC - An introduction for the survey statistician [PDF]

open access: yes, 2018
The rapid development of computing power and efficient Markov Chain Monte Carlo (MCMC) simulation algorithms have revolutionized Bayesian statistics, making it a highly practical inference method in applied work.

Quality procedures for survey transitions - experiments, time series and discontinuities

open access: yesSurvey Research Methods, 2008
To maintain uninterrupted time series, surveys conducted by national statistical institutes are often kept unchanged as long as possible. When a change is proposed to improve the methods, it may affect the continuity of these series. It is important to

Internet mobility survey sampling biases in measuring frequency of use of transport modes [PDF]

open access: yes, 2012
We develop a quantitative analysis of the biases that arise when measuring trip frequencies for a general population through an online survey instrument.

Entropy Balancing is Doubly Robust

open access: yesJournal of Causal Inference, 2016
Covariate balance is a conventional key diagnostic for methods estimating causal effects from observational studies. Recently, there is an emerging interest in directly incorporating covariate balance in the estimation.

Propensity Score Weighting for Causal Inference with Clustered Data

open access: yesJournal of Causal Inference, 2018
Propensity score weighting is a tool for causal inference to adjust for measured confounders in observational studies. In practice, data often present complex structures, such as clustering, which make propensity score modeling and estimation challenging.

Interactive Linear Models in Survey Sampling [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2014
Considered is a linear ‘interactive’ model in the context of survey sampling. This situation arises when investigator and/or supervisor interventions are contemplated in the responses.

Resampling methods in survey sampling

open access: yesLietuvos Matematikos Rinkinys, 2000
Aim of this paper is to estimate variances of the estimates of the population totals using re­sampling methods and to compare them with the known variances of the estimates.

Minimax strategies in survey sampling [PDF]

open access: yes, 1999
The risk of a sampling strategy is a function on the parameter space, which is the set of all vectors composed of possible values of the variable of interest. It seems natural to ask for a minimax strategy, minimizing the maximal risk.
