The summary statistics of my variables specifies the minimum values of each of these dummies as 0.0000E11 for instance. I am trying to implement a combined Box-Cox and Box-Tidwell estimation which requires that all variables are strictly positive. Shazam (my students licence) keeps returning an error code because of my dummies. I will appreciate some advise on how to overcome this problem.Fri, 30 Jan 2015 01:27:51 +0000http://community.econometrics.com/question/594/working-with-dummy-variables/Comment by SHAZAMHelp for <p>I have some dummy variables in my dataset.
