Richard W. Heck

Richard W. Heck was an American mathematician renowned for developing the "Heckman selection model," a statistical method used to address bias in research where only a subset of data is available, such as studying employed individuals when analyzing employment programs. His work helps ensure more accurate conclusions in social sciences and economics by correcting for biases arising from non-random data collection. Heck's contributions significantly advanced econometrics and statistical analysis, earning him recognition in the academic community.
