Actually it is called Heckman's 2 step model, or Heckman Two-Step Selection Correction Estimation.. He won the Nobel Prize for this in 2000, for his development of theory and methods for analyzing selective samples - Empirical Microeconomics as described here. http://www.bsos.umd.edu/econ/panagariya/apecon/ET/et18-oct00.htm M> If you: M> % cd /usr/ports M> % make search key=statistics M> you will get a long list of ports that do something to do with M> statistics.
