Patent ID: 10872084

Abstract:
A computer implemented method and a subpopulation size estimation and uncertainty quantification system (SE system) for estimating size of a target subpopulation size and quantifying size estimation uncertainty are provided. The SE system constructs an entity database including unique entities mapped to contacts retrieved from a contact database. The SE system receives a query defining target attributes of entities of the target subpopulation from a user device. The SE system estimates size of the target subpopulation delimited by the query by determining a first estimate of the size of the target subpopulation matching the target attributes by performing a mark and recapture estimation, and by determining a second estimate of the size of the target subpopulation matching the target attributes by performing a catch per unit effort estimation. The SE system quantifies the uncertainty of the target subpopulation size obtained from the determined estimates by determining and adjusting variances of the determined estimates.
