Students need to have passed the course Survey Methodology, and have obtained 42 ECTs in the Statistics and Data Science programme.
Due to limited capacity at Statistics Netherlands, it is possible that only students are admitted to this Module when it is clear that the student has place for his/her internship and thesis at Statistics Netherlands.
The EMOS course module takes place in the first and second semester of the second year. The course has seven parts.
1. Aspects of Official Statistics (lecturer Carina Fransen, Statistics Netherlands). The aim of the course is to give insight into the relevance of official statistics for society, to give an overview of the most important international organisations and their respective roles. Special attention will be paid to the European Statistical System, its legal basis, confidentiality laws and the European Statistics Code of Practice (among which quality of statistics).
2. Sampling and Estimation (lecturers Barry Schouten, Utrecht University and Statistics Netherlands, and Marc Smeets, Statistics Netherlands). The aim is to give insight into the design of surveys and into statistical inference based on survey data, considering population and sampling frames, sampling designs, designs of survey experiments, adaptive survey design, sampling and non-observation error, nonresponse reduction and adjustment methods and small area estimation.
3. Statistical Data Editing (lecturer Ton de Waal, Statistics Netherlands). The aim is to give insight into typical data editing and item non-response problems in official statistics and methods for dealing with them. Various imputation methods for dealing with missing data will be discussed.
4. Administrative and Big Data (lecturers Bart Bakker, Statistics Netherlands, and Piet Daas, Statistics Netherlands). The aim is to give insight into the possibilities and typical quality problems of administrative and Big Data sources and methods for dealing with them.
5. Data Management in Statistical Production (lecturer Mark van der Loo, Statistics Netherlands). The aim of the course is to give an overview of representation and processing of statistical data both on a technical and on a logical level, including the relation with enterprise architecture concepts, the production models usual in official statistics (e.g. metadata management, GSBPM) and monitoring and evaluating data quality.
6. Statistical Disclosure Control (lecturer Peter-Paul de Wolf, Statistics Netherlands). The aim is to give insight into the relevance and techniques to prevent the disclosure of sensitive information in tables and micro data. Also techniques to assess the risk of disclosure of sensitive information will be discussed.
7. Interpretation and Presentation of Official Statistics (lecturer Edwin de Jonge, Statistics Netherlands). The aim is to understand methodological issues and to interpret correctly the outcomes in some important fields of official statistics (National Accounts, Input-output tables, Price statistics, Beyond GDP, poverty and inequality, unemployment, migration) and to give knowledge and tools for an effective way of presentation of data in tables, charts and advanced visual graphics.
After taking this course the student
understands the role of National Statistical Institutes;
has gained knowledge on methods applied at these institutes and is able to apply them in practical situations;
gained experience in writing reports for both specialist and non-specialist audiences.
Mode of Instruction
A combination of self-study, lectures, lab and live-coding sessions.
100% attendance is required for the lectures, lab and live-coding sessions (see the latest version of the time schedule).
Testing will be done in two different ways: by means of assignments (40%) and by means of a written exam (60%).
For all topics, except “Aspects of Official Statistics”, one or more individual assignments will be given. For the above topics 2 - 7, a mark between 1 and 10 will be given based on on one assignment for topics 2,3,4,6,7, and the average of two home-assignments for topic 5. The average of these 6 marks will be the final mark for the assignments. That final mark for the assignments will constitute 40% of the total grade.
Written Exam (60%).
The lectures mostly take place at Statistics Netherlands (some of the lectures may also take place at Utrecht University) --> timetable to be added soon.
Also, see the Leiden University students' website for the Statistics and Data Science programme.
