Distribution based outlier detection in univariate data
Two univariate outlier detection methods are introduced. In both methods, the distribution of the bulk of observed data is approximated by regression of the observed values on their estimated QQ plot...
A general formulation of the secondary cell suppression problem
Statistical agencies have to ensure that respondents’ private information cannot be revealed from the tables they release. A well-known protection method is cell suppression, where values that...
Producing historical time series for STS-statistics in NACE Rev.2
This contribution discusses possible scenarios and methodologies for the national statistical agencies for backcasting the new classification scheme (NACE Rev. 2.0) in existing time series of...
Edit rules and the strategy of Consistent Table Estimation
The method of repeated weighting aims at obtaining numerical consistency among tables estimated from different surveys. However, in its common form, it does not take into account the existing edit...
Making the Unused Labour Force Work: Assessing the Facts for The Netherlands
This paper identifies a broad concept of unused labour force. This concept can be related to the transitional labour market theory. It is next reviewed in the light of economic studies using a...
An emperical evaluation of PRAM
PRAM (Post Randomization Method) is a disclosure control method for microdata, introduced in 1997. However, it has not yet been applied extensively by statistical agencies. This is partly due to the...
Scanner Data on Durable Goods: Market Dynamics and Hedonic Time Dummy Price Indexes
Hedonic methods are a promising tool when calculating price indexes for products experiencing rapid technological change. In this paper several hedonic time dummy price indexes are calculated for...
Time use changes in the Netherlands: The analytical strength of a time-use module
This paper first summarizes the discussion around the construction of a household satellite account and then continues to present the extension of the Dutch National Accounts with a time-use module....
Measuring R&D Output and Knowledge Capital Formation in Open Economies
Contrary to mineral exploration, computer software development and literary or artistic work, Research and Development is in the present SNA-1993 not considered as an activity leading to the creation...
Nonresponse Adjustment in Household Surveys
Nonresponse is a recurring problem in household surveys in many countries. Response rates of Statistics Netherlands surveys often vary between 50% and 60%. Research shows that nonresponse is usually...
Improving timeliness of industrial short-term statistics using time series analysis
The aim of this study was to improve the timeliness of the monthly statistics on sales development in the Dutch manufacturing industry. The focus was on producing timely indicators in the presence of...
Economic circumstances and union dissolution of couples in the 1990s in the Netherlands
This paper investigates the role of economic determinants in the dissolution of recently formed marital and non-marital unions. The economic determinants studied are women’s and men’s personal income...
Nonresponse Analysis of the Integrated Survey on Living Conditions (POLS)
This paper analyses the nonresponse of the Integrated Survey on Living Conditions, a large continuous survey of Statistics Netherlands. For this survey, more auxiliary variables were available than...
Adjustment for Bias in the integrated survey on household living conditions (POLS) 1998
Estimates for population statistics can be seriously biased in case response rates are low and the response to a survey is selective. Methods like poststratification or propensity score weighting are...
Imputation for economic data under linear restrictions
In this paper we propose a new approach to impute data under linear restrictions. If the data are normally distributed we will use simulations from the standard normal distribution. If the data are...
Automatic edit and imputation for business surveys: The Dutch contribution to the Euredit project
Statistics Netherlands participated in the EUREDIT project, a large international research and development project on statistical data editing and imputation that lasted from March 2000 till February...
A simple branching scheme for solving the error localisation problem
In this paper we present a new algorithm for solving the error localisation problem for a mix of continuous and categorical data. This algorithm is based on constructing a binary search tree.
Simulation studies of Repeated weighting
Repeated weighting provides a method to obtain sets of table estimates with numerically consistent margins from combinations of registers and surveys. It is based on repeated application of the...
Using national registrations to correct for selective non-response. Political preference of ethnic groups
This paper deals with non-response bias, discussing a few approaches in this field. It is demonstrated that nonresponse bias as to voter turnout is lower in a survey on living conditions than in a...
A design-based procedure for the analysis of experiments embedded in complex sample surveys
Experiments embedded in ongoing sample surveys are particularly appropriate to test effects of alternative surevey methodologies on estimates of finite population parameters.
Estimating consistent table sets: position paper on repeated weighting
Statistics Netherlands is presently making a considerable effort in combining data from administrative sources with, mainly household, survey data. By making efficient use of register data,...
An emperical comparison of BRR and linearization variance estimators
A simulation study is performed to compare linearization and balanced repeated replication (BRR) variance estimates in various situations.
Computational Results For Various Error Localisation Algorithms
Over the last few years several algorithms for solving the so-called error localisation problem have been developed at Statistics Netherlands. For six data sets involving numerical data we present...
Remote Access Systems for Statistical Analysis of Microdata
Discussion paper A remote access system is a facility where users can submit queries for statistical information from their own computer. These queries are handled by the statistical agency and the...
Are Dutch Services Industries Becoming More Productive? Explorations on Micro-data
Statistics Netherlands is planning to set up a system of productivity statistics. An innovative approach is to directly build up productivity indices from data at the level of the individual firm. To...
