Matt Barens <matstata@yahoo.com> asked me to forward the following to the list: ------------------------------------------------------------------------------ Hello Statalisters, I have the following problem(s) and I was wondering if there was a way to deal with this in stata 7 (although if there is a way to deal with it in stata 8 I would also be interested in finding out how). I want to do the following analysis. The dependent variable is dollar amount in checking account. This is censored, because about 15% of the sample has a missing value since they do not own a checking account. The main explanatory variable I use and am interested in is whether the person owns a credit card or not. Nonetheless, there is some potential endogeneity here (e.g. people who spend more may both decide to hold a card and have more money in their checking accounts). I have the following 3 questions: 1. First, I have some variables that I could use to instrument for credit card holding. However, it is a binary variable, so normally I would want to do a probit in the first stage, but I dont think the ivreg command allows for this. Do I just forget about probit? 2. Second, how does one do iv analysis in a censored regression? 3. Third, there is one more issue. In order to hold a credit card, you normally first need to have a checking account (and recall that it is account ownership or not that creates the censoring in the regression). So even if one solves the above two issues, how do I deal with this additional one? thank you much for any ideas you might have on this, matt --Jeff jpitblado@stata.com * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
