Hi,
I am new to Stata. I am estimating a hazard model of unemployment duration. The dataset is a two-year monthly panel. The first observation starts in 01/2006 for each individual and indicates if the person is unemployed or not. However, if she is unemployed in 01/2006, there is no way to know how long she has been unemployed. That is, I have lots of individuals without information on their true onset of risk. My question: is there any way to introduce this situation to Stata? Any help would be much appreciated. Thanks
