Upcoming International Workshop:
 

Statistical Models and Diagnostics for Population Size Estimation Methods


 2 – 5 March 2015
Shiraz, Iran

Overview
What we cover

In first day, we start by explaining what a population estimation study is. We explain the type of estimates expected from a populationsize estimation (PSE) study. Giving examples, we will discuss the methods to measure uncertainty around PSE estimates considering both random and systematic errors. We will provide illustrate examples on how bootstrap re-sampling and Monte Carlo methods can be applied to measure uncertainties in general and then particularly in PSE estimates. Then, we will discuss different type of missing, explore the methods to determine their effect, adjust or reduce their effects on PSE estimates. Overall, our approach is to first explore bootstrap and Monte Carlo in general settings and then illustrate their applications for PSE studies. 
In second day, we introduce network scale up method, explain the assumptions and discuss the common mistakes and how to avoid them. We introduce participants to the analysis package, which automates the social network size estimation, measuring the effect of biases (such as visibility and popularity) and missing rate and impute missing to provide unbiased estimates.
In third day, we focus on another method, capture-re-capture and its variations such as one round or network-based estimators. We discuss the basic analysis, stratifications and log-linear regression models and introduce participants to the analysis packaged developed for this purposes.
The fourth day we introduce other population size estimation methods such as Multiplier and its variations, and Random Proxy Respondents. We also provide methods to estimate the variance for each method and provide uncertainty analysis for each estimate using bootstrap techniques.

At the conclusion of each method, we discuss assumptions and diagnostics related to that method and how to deal with them. Throughout the workshop we focus on concepts, the statistical package on how to do the proper analysis rather than the formulas.

What we do not cover
Implementing population size estimation includes formulating research questions, define the specific objectives and target populations, determining appropriate and feasible methods, staff training and supervision, resource management, data collection and monitoring, and then performing the statistical analysis. This workshop focuses only on the last step, which is data analysis.

·         Diagnostics for indirect social network size estimation

·         Bias analysis and correction factors for a network scale up study

·         Missing data and imputation techniques in network scale-up method

·         Performing a network scale up analysis using Excel / SPSS

Day – 3

Who should attend
This workshop is intended for researchers, statisticians and graduate students, and anyone with an interest in understanding or performing data analysis for population size estimation studies. Our approach is conceptual rather than mathematical, and participants with basic knowledge on statistics and skills in working with analysis software (Excel and SPSS) should be able to fully understand the materials.
