CoverMethodologies used in surveys of road freight transport in Member States, EFTA and Candidate countries - 2017 edition

The present document describes the methods used by Member States, candidate and EFTA countries in their surveys on road freight transport statistics. Part I describes national methodologies for data collection. This information is based on questionnaires completed by the reporting countries. Data in these questionnaires refer to the first quarter of 2016. Part II includes summary tables, with the basic information on sampling, response rate, register quality and precision of results of the surveys. Data on the registers used to draw the sample and the sampling methodology are relevant for the surveys conducted in the first quarter of 2016, while the main characteristics given for each country refer to the years 2015 and 2016, according to data availability. ‘Methodologies used in surveys of road freight transport in Member States, EFTA and Candidate Countries’ is published in English only.

CoverAnalysis of the most recent modelling techniques for big data with particular attention to Bayesian ones

In this report we describe various methods suited for the analysis of linear models with a very large number of explanatory variables, with a special emphasis on Bayesian approaches. We next consider some non-parametric and/or non-linear methods suited for applications with big data, such as random trees, random forests, cluster analysis, deep learning and neural networks. Finally, we survey techniques for summarizing the information in large (possibly sparse) datasets, forecast combination approaches, and techniques for the analysis of large mixed frequency datasets.

CoverProviding comparable information to assess global financial stability risks

The Conference of European Statistics Stakeholders (CESS) brings together European stakeholders such as official statisticians, methodologists, private data producers/providers and data users. The conference, held biennially, gives participants an opportunity to discuss user needs and exchange good practices in statistical production and outreach. It is also an opportunity to illustrate innovative ways of visualising and communicating statistics and promote new methodological ideas in data conception, collection and analysis.

This Statistical Report contains the full-length version of the paper “Providing comparable information to assess global financial stability risks”, presented at CESS 2016 (Budapest 20-21 October 2016) by Bruno Tissot (Head of Statistics & Research Support at the Bank for International Settlements).

Manual de Eurostat sobre estimaciones rápidas

CoverHandbook on Rapid Estimates

In an ever more interconnected and interdependent world, where time is increasingly of the essence, more reliable and up-to-date data are needed to enable and support the process of effective decision making, e.g. via rapid estimates.

This handbook provides an overview of the different types of rapid estimates and the statistical and econometric methods for their construction. It also offers guidance for the implementation of rapid estimates in practice and their quality assessment. [+]

CoverTransatlantic trade in services: Investigating bilateral asymmetries in EU-US trade statistics

The EU and the US are the most prominent economic partners in international trade in services in the world. Persistent bilateral asymmetries in their trade statistics remain however a substantial issue that challenges conclusive reading of the data. This paper presents an overview of findings about asymmetries to international trade in services data of the EU and the US, and concludes on a need for higher coordination of the implied statistics.

CoverCompendium of methodological clarifications — ESSPROS, European system of integrated social protection statistics — 2017 edition

The European System of Integrated Social Protection Statistics (ESSPROS) aims to collect comparable statistical data by enforcing a common methodology. Given the different national social protection systems and their continuous adaptation to emerging needs, inevitably there are cases of interventions for which the methodology does not provide clear guidance on whether or not they should be included in ESSPROS and how they should be reported. This document provides a compendium of the analysis performed in order to give methodological clarifications, including cases where changes to the ESSPROS methodology were proposed and adopted by the Working Group on Social Protection Statistics.

CoverFiltering techniques for big data and big data based uncertainty indexes

This work is concerned with the analysis of outliers detection, signal extraction and decomposition techniques related to big data. In the first part, also with the use of a numerical example, we investigate how the presence of outliers in the big unstructured data might affect the aggregated time series. Any outliers must be removed prior to the aggregation and the resulting time series should be checked further for outliers in the lower frequency. In the second part, we explore the issue of seasonality, also continuing the numerical example. Seasonal patterns are not easily identified in the high frequency series but are evident in the aggregated time series. Finally, we construct uncertainty indexes based on Google Trends and compare them to the corresponding Reuters-based indexes, also checking for outliers and seasonal components. [+]

CoverSelected papers from the 2016 Conference of European Statistics Stakeholders — Special issue

The Conference of European Statistics Stakeholders (CESS) brings together European stakeholders such as official statisticians, methodologists, private data producers/providers and data users. The conference, held biennially, gives participants an opportunity to discuss user needs and exchange good practices in statistical production and outreach. It is also an opportunity to illustrate innovative ways of visualising and communicating statistics and promote new methodological ideas in data conception, collection and analysis.

This special Statistical Working Papers (SWP) issue presents selected papers from CESS 2016, held in Budapest on 20-21 October 2016. The papers highlight many of the current and future themes for ensuring good-quality statistics that are fit for use. [+]

CoverEU guidelines for the International Classification of Crime for Statistical Purposes — 2017 edition

Eurostat deals with a great variety of legal concepts and criminal justice systems among European countries in its annual data collection on crime and criminal justice. A common classification of offences will strengthen comparability and consistency of crime and criminal justice data and improve analytical capabilities at the national, European, and international levels. A common framework based on internationally agreed concepts, definitions, and principles to group all kinds of criminal offences into useful statistical categories already exists in the International Classification of Crime for Statistical Purposes (ICCS). This common framework is applicable for all forms of crime data at all stages of the criminal justice process as well as for data collected in crime victimization surveys. The data on criminal offences published by Eurostat are already classified according to the ICCS. However, variations of national criminal law and the lack of common definitions between European countries still limit the comparability of crime data. This booklet presents the structure of the ICCS, its classification principles and its relations to existing classifications, to facilitate the implementation of the ICCS. It provides a brief overview of concrete organizational and technical tasks for a successful implementation of the ICCS at the national level, which should engage all crime data users and data providers. In addition, an implementation strategy through the creation of a correspondence table, a tabulation of all offence categories in the ICCS linked to all offences on the national level, is briefly described.
