PSA-BARMM employee completes Training on Small Area Estimation
Rubikha I. Ishmael, Statistical Specialist II of PSA-BARMM, completed the Training on Small Area Estimation (SAE) conducted by the Philippine Statistical Research and Training Institute (PSRTI) for Philippine Statistics Authority (PSA) employees last 22 to 26 July 2019 at PSRTI, Quezon City.
The training course aims to provide the participants with an overview and understanding of concepts and methods in small area estimation, their motivation and applications. The said training will let the participants to be able to familiarize on the different methods for small area estimation; understand how both conventional and innovative data sources can be used to implement small area estimation methods; understand the uses and limitations of the different methods; understand the circumstances when the different methods are applicable; understand how the results of the different methods should be interpreted; gain skills in mapping local area statistics; and learn how to do small area estimation using real life data. The course is intended for statisticians, particularly the survey practitioners. Knowledge of multiple linear regression and analysis of variance techniques, proficiency in computer operations and STATA software are the recommended background of the participants. PSA – Human Resources Division (HRD) provided the list of participants that are selected based on their training profile and qualifications set by PSRTI.
Before the training proper, Praxedes R. Peña, Chief of theTraining Division of PSRTI gave an opening message to welcome the participants to the five-day training.

During the training proper, the first topic was all about the Basic Concepts and Principles of SAE and Introduction to Different SAE Approaches which were discussed by Arturo Martinez Jr., Statistician of Statistics and Data Innovation Unit, Economic Research and Regional Cooperation Department – Asian Development Bank (ADB). This was followed by a workshop.
Joseph Albert Niño Bulan, Associate Statistics Analyst of Statistics and Data Innovation Unit, Economic Research and Regional Coordination Department – ADB, discussed the Direct Survey Estimation and gave review on using STATA software. On the other hand, Calibration and Reweighting and Empirical Best Linear Unbiased Prediction (EBLUP) were discussed by Martinez.
Martinez also discussed the Other Model-Based SAE Methods and Completing Conventional SAE Techniques with Innovative Data Sources, while the Introduction to Night Time Light (NTL) and Rural Accessibility Index (RAI) were discussed by Ron Durante, Consultant of Statistics and Data Innovation Unit, Economic Research and Regional Coordination Department – ADB. These lectures were also followed by a series of workshops. Durante continued the training through the discussion on Extracting NTI Values and Calculating RAI using QGIS, which were also followed by a workshop. Moreover, Martinez ended the training with the lecture on Measuring Economic Growth from Outer Space.
The groups were assigned with a final workshop incorporating all of the lessons taken during the five-day traning. Their outputs were presented during the last day of the training and were critiqued by assigned officials.
