After a little search I have found how to convert .dta from stata 13 to be used in stata 10-12. Note that if you are using stata 10.0 you will need first to update to stata 10.1 by runing “update all”. The update is free.
You need to use command called use13 written by Sergiy Radyakin (email@example.com ). Installation is
Option 1: in Stata’s command prompt type findit use13 Then click on the link for -use13- in the Stata’s viewer and click the -install- link.
Option 2: in Stata’s command prompt type the following: ssc install use13
Usage (quotation marks not necessary if the path to the file do not contain spaces): use13 “…/path/mydata13.dta”
