Establishing the accuracy of online panels for survey research

This study compares two different techniques in a time series small area application: state space models estimated with the Kalman filter with a frequentist approach to hyperparameter estimation, and multilevel time series models estimated within the hierarchical Bayesian framework. The application chosen is the Dutch Travel Survey featuring level breaks caused by the survey redesigns, as well as small sample sizes for the main publication domains. Both models require variances of the design-based domain estimates as prior information. In practice, however, only unstable estimates of the design-based variances are available. In this paper, excessive volatility and a possible bias in design-based variance estimates are removed with the help of a state space model. The multilevel and state space modelling approaches deliver similar results. Slight differences in model-based variance estimates appear mostly in small-scale domains and are due to neglecting uncertainty around the hyperparameter estimates in state space models, and to a lesser extent due to skewness in the posterior distributions of the parameters of interest. The results suggest that the reduction in design-based standard errors with the hierarchical Bayesian approach is over 50% at the provincial level, and over 30% at the national level, averaged over the domains and time.

In this paper the question is addressed how alternative data sources, such as administrative and social media data, can be used in the production of official statistics. Since most surveys at national statistical institutes are conducted repeatedly over time, a multivariate structural time series modelling approach is proposed to model the series observed by a repeated surveys with related series obtained from such alternative data sources. Generally, this improves the precision of the direct survey estimates by using sample information observed in preceding periods and information from related auxiliary series. The concept of cointegration is applied to address the question to which extent the alternative series represent the same phenomena as the series observed with the repeated survey. The methodology is applied to the Dutch Consumer Confidence Survey and a sentiment index derived from social media.

Study of the possibilities to compile figures on the consequences of the long-term care reform. Commissioned by: Ministry of Public Health, Welfare and Sport

Non-probability samples provide a challenging source of information for official statistics, because the data generating mechanism is unknown. Making inference from such samples therefore requires a novel approach compared with the classic approach of survey sampling. We propose a framework based on predictive inference and discuss three classes of methods. We conduct a simulation study with a real-world data set.

The research presented in this paper has been done in the context of the further development of the methodology of calculating the Hospital Standardised Mortality Ratio (HSMR) in the Netherlands. It has been funded by Dutch Hospital Data (DHD). The goal of this research is to investigate the effect of adding post-discharge mortality to the HSMR. The advantage of adding post-discharge mortality, is that the mortality indicator becomes less dependent on the discharge policies of hospitals. Pouw et al. (2013) have investigated the possibilities and effects of adding post-discharge to the mortality indicator in the Netherlands. They concluded that this would lead to an improvement of the indicator. However, they did not investigate what the optimal period should be in which the post-discharge mortality is taken into account, whether or not the length of the period should differ between diagnosis groups and whether this period should be from admission or from discharge. These questions have been investigated by Statistics Netherlands and the results are presented in this paper (in Dutch).

Although the term expat is well-known, no universal definition of this group of foreign employees is available. Statistics Netherlands has published a research paper, exploring the possibility to define the number of expats in the Netherlands based on its integrated datasets. The study concludes that not all features of expats are available in Statistics Netherlands data. A rough definition of expats can be drawn up: foreign-born employees with a high wage who do not have the Dutch nationality.

In recent years, the importance of the households sector in measuring economic welfare has increasingly been recognised, and the development of additional indicators to measure inequalities is suggested. This article reports the work done by Statistics Netherlands concerning the development of such indicators. National accounts data has been combined with distributional information to divide income, consumption and wealth over household groups. This paper presents the preliminary results for the standard of living.

Assessment of selectivity of Big data sets is generally not straightforward, if at all possible. Some approaches are proposed in this paper. It is argued that the degree to which selectivity – or its assessment – is an issue, depends on the way the data are used for production of statistics. The role Big data can play in that process ranges from minor over supplementary to vital. Methods for inference that are in part or wholly based on Big data need to be developed, with particular attention to their capabilities of dealing with or correcting for selectivity of Big data. This paper elaborates on the current view on these matters at Statistics Netherlands, and concludes with some discussion points for further consideration or research.

We carried out an analysis at a sectoral level, and tested a score of different, potentially relevant, weather effects. The influence on GDP was then computed by aggregation. We found that, on a quarterly basis, several industries exhibit a significant weather effect. As a result of sectoral effects having opposite signs, the net effect of unusual weather on GDP as a whole is rather modest for some periods, while for other periods, the effect is more substantial.

The estimation of measurement effects (MEs) of survey modes in the presence of selection bias poses a great problem to methodologists. We present a new method to estimate MEs by means of “within-subject designs”, in which the same sample is approached by two different modes at two subsequent points in time. The decomposition of mode effects into MEs and selection biases is illustrated for key statistics from the Dutch Crime Victimization Survey using data from a large-scale within-subject experiment conducted within Statistics Netherlands’ project Mode Effects in Social Surveys (abbreviated to MEPS in Dutch).

Linear structural equation models (SEMs) are widely used to assess the validity and reliability of survey variables. When population means or totals are of interest, it is also important to assess whether the observed variables contain an intercept bias. Unfortunately, standard identification procedures for SEMs define an arbitrary metric for the latent variables, which prevents the estimation of valid latent means and intercepts in a single population.

This paper explores the use of matched samples as an alternative for estimators based on surveys suffering from a substantial amount of nonresponse.

We describe the role of information management in redesign programs: why it is needed, how it is at present being developed through international cooperation in the Generic Statistical Information Model (GSIM) project, and we give some examples how information management has been used in practice at Statistics Netherlands. We conclude that GSIM is necessary for more extensive usage of big data sources, for interoperability of statistical tools and for sharing tools between NSIs.

In 2011, a large-scale mixed-mode experiment was linked to the Crime Victimisation Survey (CVS). This experiment consisted of a randomized allocation of sample persons to the four survey modes Web, mail, telephone and face-to-face, and a follow-up using only interviewer modes face-to-face and telephone. The aim of the experiment was to disentangle mode-specific selection- and measurement effects. The analyses show that contact effort has little impact on the size of measurement bias and a modest impact on the size of selection bias. Also, interviewer performance plays just a small role in the size of both biases. From these results, we conclude that contact effort and interviewer performance do not have a simultaneous impact on nonresponse and measurement error.

Commissioned by: Ministry of Social Affairs and Employment.

Assessing the impact of mode effects on survey estimates has become a crucial question due to the increasing appeal of mixed-mode designs. Despite the advantages of a mixed-mode design such as lower costs and increased coverage, there is sufficient evidence that mode affects may sometimes be large relative to the precision. They may lead to incomparable statistics in time or over population subgroups and they may increase bias. Adaptive survey designs offer a flexible mathematical framework to obtain the optimal balance between survey quality and costs. In this paper we employ adaptive designs in order to minimize mode effects. We illustrate our optimization model by means of a case study on the Dutch Labour Force Survey.

This paper presents and discusses some new results on the second-order inclusion probabilities of a systematic probability proportional to size sample drawn from a randomly ordered list, also called randomized PPS sampling. It is shown that some standard approximations of these second-order inclusion probabilities meant for relatively small sample sizes, need not be valid when the sample size n is of the same order as the population size N. In addition, it is shown that under a number of assumptions the variance formulas for rejective Poisson sampling can be applied to randomized PPS sampling designs when both n and N-n are large.

Various claims have been made regarding the benefits that EnterpriseArchitecture (EA) delivers for both individual systems development projects and the organization as a whole. This paper presents the statistical findings of a survey study(n=293) carried out to empirically test these claims. First, we investigated which techniques are used in practice to stimulate conformance to EA. Secondly, we studied which benefits are actually gained. Thirdly, we verified whether EA creators (e.g. enterprise architects) and EA users (e.g. project members) differ in their perceptions regarding EA. Finally, we investigated which of the applied techniques most effectively increase project conformance to and effectiveness of EA. A multivariate regression analysis demonstrates that three techniques have a major impact on conformance: carrying out compliance assessments, management propagation of EA and providing assistance to projects. Although project conformance plays a central role in reaping various benefits at both the organizational and the project level, it is shown that a number of important benefits have not yet been fully achieved.

This paper gives alternative derivations for the standard variance formulas in two-stage sampling. The derivations are based on a direct use of the statistical properties of the sampling errors in the second stage. For the ease of exposition we examine the specific case that simple random sampling is used in both stages. These derivations might be useful for readers looking for more elementary approaches to two-stage sampling.

Numerical and categorical data used for statistical analyses is often plagued with missing values and inconsistencies. In many cases, a number of missing values may be derived, based on the consistency rules imposed on the data and the observed values in a record. The methods used for such derivations are called deductive imputation. In this paper, we describe the newly developed deductive imputation functionality of R package deducorrect.

Analyses of categorical data are often hindered by the occurrence of inconsistent or incomplete raw data. Although R has many features for analyzing categorical data, the functionality for error localization and error correction are currently limited. The editrules package is designed to o er a user-friendly toolbox for edit de nition, manipulation, and error localization based on the generalized paradigm of Fellegi and Holt.

Competition can be good or bad for innovation. In this paper a model is tested in which an increase of competition stimulates innovation when competition is low, but where innovation is discouraged when the level of competition goes beyond a certain threshold. We use industry- as well as firm-level data, and find evidence for such a threshold using two different competition measures.

At the request of RWI (Council for Work and Income), Statistics Netherlands’ Centre for Policy Related Statistics has composed a set of tables with information on the labour market of position of 45–64 year-olds.
