Helmholtz decomposition for digraphs
The present paper is about a concept from analysis, namely the Helmholtz decomposition of vector fields that can be translated into a similar concept for certain directed graphs, also called the...
SDC and special focus groups: a European perspective
Publications on small, special focus groups call for accurate application of statistical disclosure control. To that end, perturbative methods may be useful. Proper communication thereof is...
CBS introduces new energy price measurement method
From June 2023, Statistics Netherlands (CBS) will employ a new method to measure the energy prices paid by consumers. The aim is to derive a more accurate inflation rate.
International trade in goods statistics changed as of 2023
The international trade in goods statistics describe the monthly development of the import and export of goods.
Elastic energy of networks
The paper is about invariants of networks by labeling and relabeling its nodes or arcs. These invariants can be used to classify networks as to their complexity, or to distinguish non-isomorphic...
Redistribution of mass and probabilities
Models to transport goods or matter can also be used to disaggregate probability measures defined on 2D-tables.
Ensembles of networks
About viewing a given network as a realization of a network which belongs to a certain set of networks, called an ensemble. It is comparable to viewing a population as being generated from a...

CBS and UvA in collaboration to solve social problems
It sounds like science fiction: a ‘digital twin’ of society that policy-makers can use to resolve complex social problems.
Topological anonymity in networks
Statistics Netherlands has been investigating Network data as a source of new statistics. This implies new questions in the area of statistical disclosure control. In this paper a theory for...
Citizenship in context: Naturalisation and residential environment of immigrants in the Netherlands
Dissertation on the interaction between the living environment and naturalization of immigrants after they have settled in the Netherlands.
PhD student investigates causes of premature birth
On 18 January 2022, Eduardo Villamor Martinez obtained his PhD cum laude from Maastricht University.
On Kalman filtering and variances after single and multiple imputation
Using Kalman equations, we derive straightforward formulas for the total imputation variance for several imputation methods commonly used in regression analysis and (un)equal probability sampling...
Complexity and simplification of networks (v2)
The paper deals with two topics: the quantification of the complexity of networks (graphs and digraphs) and the simplification of networks by identifying their most important parts (nodes and arcs /...
Including migration in hedonic valuation: earthquakes
This paper is an attempt to estimate the willingness to pay for earthquake reduction in and around the province of Groningen (2012-2018), whilst using a discrete choice model to incorporate...
An estimator for ratios of Poisson distributed quantities
A common task for national statistical institutes is to estimate the size of a subpopulation, with certain specific characteristics, as a proportion of a larger population or subpopulation. This...
How the mathematics of complex systems contributes to statistics
On Wednesday 20 October 2021, Professor Frank Pijpers gave his inaugural lecture on Empirical explorations of a complex society at the University of Amsterdam.
State space methods for official statistics and climate modelling
Multivariate state space methods for estimating official statistics and modelling climate data.

Estimation of antenatal care coverage in Bangladesh
Method of estimating annual figures based on surveys that become available every three to four years.
Assessing Public Sector Productivity
A methodological study into the productivity of the Dutch public sector with calculations for the courts, public prosecution service and the police

Evaluating and improving a text classifier for subpopulations: the case of cybercrime.
Sensor Data Challenge 2021: experimenting with smart sensors
The third Sensor Data Challenge took place on 22 and 23 April 2021.
