FPEM

FPEM estimates family planning indicators for individual countries or smaller geographic areas using the Family Planning Estimation Model (FPEM) framework and fixed non-population-specific parameters from prior global model runs, implemented via the fpemlocal R package.

Key Features:

• Bayesian Hierarchical Modeling: Employs a Bayesian hierarchical model with country-specific time trends to estimate contraceptive prevalence and unmet need for family planning.
• Integration with FPEMglobal: Uses non-population-specific parameters fixed from global FPEM outcomes to maintain consistency with FPEMglobal.
• Data Handling: Includes and accepts comprehensive datasets such as survey data, country unit data, and population counts for one-country analyses.
• Aggregation Capability: Allows aggregation of estimates across multiple populations.
• Computational Efficiency and Accuracy: Emphasizes computational efficiency and accuracy for single-country or small-area runs.

Scientific Applications:

• Family Planning Indicators Estimation: Produces estimates of contraceptive prevalence and unmet need within specific countries or regions.
• FP2020 and Track20 Support: Supports the Track20 Family Planning Estimation Tool and monitoring activities under the FP2020 initiative.

Methodology:

Accepts package-provided and user-specified databases as input, processes these inputs through a Bayesian hierarchical model with country-specific time trends using fixed non-population-specific parameters from prior global FPEM runs, and supports aggregation of resulting estimates across populations.
