Course Content
The overall aim of this course is to provide participants with the knowledge required to project and realize a sample survey with attention to the most common sources of non-sampling errors.

Learning Objectives
After completing the course the students should be able to:
- correctly design and analyze simple and complex sampling strategies for the study of specific phenomena;
- analyze the problems associated with the presence and statistical treatment of non-sampling errors, with particular attention to the non-response problems.
Prerequisites
Preliminary teachings: "Inferenza statistica e metodi computazionali" and "Probabilità e matematica per la statistica"
Teaching Methods
Lectures and classrooom exercises
Type of Assessment
The evaluation is based on three elements:
- Written exam including both practical exercises and questions on theory;
- Project based on the analyses of data
- Oral exam: the student who received a sufficient evaluation in both the written exam and project will be admitted to the oral exam; the oral exam covers the theory and interprertation and includes the discussion of the project; at the end of the oral exam, a final mark will be given
Course program
The basic concepts in sampling theory for finite populations and the Horvitz-Thompson's estimator
Most commonly used probabilistic sampling designs: simple random sampling with and without replacment, stratified sampling, cluster sampling, two-stage sampling, systematic sampling, probability-proportional-to-size sampling, complex sampling designs
Types of non-probability sampling.
Sample Size and Sample Allocation
Estimation using known auxiliary variables: the ratio estimator, the difference estimator, the regression estimator, the post-stratified estimator, calibration and weighting estimators, estimation for domains.
Non-sampling errors; frame imperfections; unit and item nonsponse; statistical treatment of non-sampling errors.
Designing samples for repeated surveys.
Variance estimation for complex sampling design.
Linear and generalized linear models with data from complex surveys.
Missing data: assumptions and treatment. Multiple imputation.
