[R] Need help on running Heckman Correction Estimation using R
Team, I am trying to resolve the self-selection bias of a sample in an experiment and would like to run the Heckman Correction Estimation using R. Can someone help me with the R-Code... I tried searching for the discussion, but not successful. Thanks in advance, Best, Kishore/.. http://kaykayatisb.blogspot.com [[alternative HTML version deleted]]

Hi Kishore and Justin, The sample selection stuff has been separated from the micEcon package about one year ago. It is available in the sampleSelection package [1,2,3] now. The sample selection package is thoroughly described in a (freely available) paper published in the Journal of Statistical Software [4]. We recommend using the "selection" command rather than the "heckit" command, because the former can be used to estimate the model not only by the two-step method but also by ML.
