Quick Summary

The Heckman correction is a statistical method developed by economist James J. Heckman to address sample-selection problems in data analysis. When a sample used for analysis does not accurately represent the real-world population, it can lead to flawed conclusions and policy decisions.1

The Heckman correction is a two-step statistical approach designed to adjust for these sampling errors, thereby improving the reliability of the analysis. James J. Heckman, a Nobel laureate in Economics, is recognized for his work on the microevaluation of labor-market programs and for developing theories and methods to analyze individual and household behavior. His research has been instrumental in understanding how individuals make choices regarding employment, residence, and marital status.1
