Buying the book by Hamilton was an excellent first step for Obi. As he works
his way through it, he will encounter issues that are unclear to him or that
simply do not work out as expected. If that is the case, Obi, come back and
ask. I was certainly glad back in the day that I could access the joint
wisdom of all Statalist members...

Just like any programming language, interpreted or compiled, Stata will 
not work if you do not use the correct syntax.  Try to find some 
examples to help you figure out (a) what is the general syntax of the 
statements in Stata, for example, concerning where to put "if" (and 
whether Stata considers it to be an option, at all), and (b) how to 
interpret the help files.  You should definitely have a working 
knowledge of Stata before sending questions to the list.

Please if I want to run an independent sample t-test with a panel data and I
want to limit it to a particular wave please what command should I use?
