Variance Estimation for Complex Survey Data and Microsimulation

Variance estimation is crucial for evidence-based policy-making. This workshop, held at the EUROMOD Winter School, focused on the importance of estimating precision in statistics. Key messages include reporting standard errors, confidence intervals, and p-values based on sample estimates, and emphasizing the significance of sample design in estimating precision. The training covered theoretical concepts and practical exercises using synthetic data reflecting real-life scenarios in EU-SILC, catering to a diverse audience with statistical competences and software knowledge.

8. Introduction Statistics & samples are a powerful tool - Need limited number of observations - Point estimate and estimate of precision However, without an estimate of its precision, a point estimate is pointless at least for evidence-based policy-making 8

9. Introduction Key messages 1. If estimates are based on samples -> estimate and report SEs, CIs & p-values 2. Always take as much as possible account of sample design when estimating SEs, CIs & p-values 3. Never delete observations from the dataset 4. Never simply compare confidence intervals 9

10. Introduction Setup of the training Some concepts and theory Hands-on exercises, based on synthetic data that reflect real situations in EU-SILC Focus is on necessities for practical implementation Targeted to diversified audience (statistical competences, knowledge of statistical software) Assume some familiarity with analysis of survey data Complementary to standard courses 10

11. Introduction Focus on getting variance estimates right Steps in applied survey data analysis Step Activity 1 Definition of the problem & objectives 2 Understanding the sample design 3 Understanding design variables, constructs, and missing data 4 Analysing the data 5 Interpreting and evaluating results 6 Reporting estimates and inferences Source: Heeringa et al., 2010, p. 9. 11

12. Introduction DAY 1 1/ Sampling variance and Total survey error 2/ Determinants of the sampling variance 3/ Estimating the sampling variance & EU-SILC sample design 4/ Ultimate cluster approach and EU-SILC sample design variables Exercises DAY2 5/ subpopulations & comparisons of samples / simulations / Exercises 6/ Conclusion; feedback 12
