如何在Stata中循环浏览Excel工作表和列表？

Question

I just started working with Stata and I couldn't figure out the following.

1. How can I loop over the lists of Excel sheets and the indices. This works fine now.

    clear all set more off local mysheets 1996 2000 2003 2007 2008 2010 local indices index1 index2 index3 foreach sheetname of local mysheets { import excel "C:\\stata\\Data.xls", sheet(`sheetname') firstrow clear foreach index of local indices{ tobit theta index, ll(0) ul(1) outreg using "C:\\stata\\results.doc" , `append' local append "append" } } 

Answer 1

Just to post as an answer (so the question doesn't appear unanswered), since it seems to be a simple coding error:

• Make sure local macro names are consistent throughout ( mysheet vs. mysheets )
• Use local macro syntax for the argument of foreach (in this case, sheetname ) inside of foreach loop

• If using a local macro to define the append option of outreg , define it before the option is called

   clear all set more off local mysheets 1996 2000 2003 2007 2008 2010 local indices index1 index2 index3 foreach sheetname of local mysheets { import excel "C:\\stata\\Data.xls", sheet(`sheetname') firstrow clear foreach index of local indices { tobit theta `index', ll(0) ul(1) local append "append" outreg using "C:\\stata\\results.doc" , `append' } }
