Hello,
I have data for a cohort of firms that started their operations in 2004 and were surveyed until 2011. However, the information about a treatment was gathered later only from 2007 to 2011. So, there is not any information about such treatment for years before 2007.
I want to evaluate the effect of such treatment on the survival time of these firm by implementing the code
I have the following question:
Should I restrict the survival analysis to the period of 2007 to 2011, and thus changing the age of firms to be 1 for those in 2007, to be 2 in 2008, ..., and be to 5 for the firms that survived until 2011?
Are there any other ways to evaluate the effect of such treatment on the survival time without restricting the sample in
?
I appreciate your help.
Best regards,
Hossein
