A Talk on “Introductory Session on Joint Program in Survey Methodology” and “Integrating Survey Data with Alternative Databases for Small Area Estimation” byDr Partha Lahiri

ABOUT THE TALK

Introductory Session on Joint Program in Survey Methodology

The founding of JPSM in 1993 resulted from an initiative of the United States Federal Statistical Agency heads, the head of the Office of Management and Budget’s Statistical Policy Office, and the chair of the U.S. President’s Council of Economic Advisors. The founders of JPSM brought together a consortium of organizations, disciplines, and researchers to provide the necessary expertise in survey research, which deals with theories and practices of various data collection and analysis activities for effective decision making. The survey research world has changed since JPSM’s founding. Examples include the rise of nonprobability surveys, the growing reliance on probability panels and the new opportunities that now exist to use unstructured data collected for various purposes. The recent renaming of our degree programs – our degree-seeking students now receive either a Master of Science in Survey and Data Science or a PhD in Survey and Data Science – and corresponding changes in our instructional programs reflect the changes that have occurred in the field. In this talk, I will provide information on JPSM’s Master of Science Degree program in Survey and Data Science.

Integrating Survey Data with Alternative Databases for Small Area Estimation

The demand for various agriculture, socio-economic, and health statistics for small geographical areas is steadily increasing at a time when survey agencies are constantly looking for ways to reduce costs to meet fixed budgetary requirements. In the current survey environment, the application of standard sample survey methods, which require a large sample, is generally not feasible for small domains, as the cost would be prohibitive. One of the key factors that leads to the success of small area estimation (SAE) methodology in many applications is the availability of strong auxiliary variables. The accessibility of Big Data from disparate sources (e.g., administrative/register records, social media data, mobile phone data, sensor data, satellite data, etc.) brings new opportunities for statisticians to develop innovative SAE methods. We will begin the lecture by discussing the challenges of producing small area estimates using sample survey data alone. We will then discuss how sample survey data can be effectively integrated with alternative databases in producing reliable small area estimates. As for illustration of SAE methodology, we will consider an application where survey data can be combined with geospatial data in producing improved estimates of crop acreage for small geographical areas.
