I updated my Stata 7 and now the endogenous option is available.  However,
I've had trouble updating the executable.  I am supposed to follow the
instructions below but it did not go well.  I had to reinstall Stata and do
the update process again but have not been able to update the  executable...

    1.  Exit Stata
    2.  Change to C:\Stata\
    3.  Copy wstata.exe to wstata.old
    4.  Copy wstata.bin to wstata.exe
    5.  Try Stata
    6.  Later, erase wstata.old if satisfied
        or copy wstata.old back to wstata.exe

Does any one know how to do this properly?  It seems very easy but...

Hi Stata list users,

If any of you have access to both Stata7 and Stata8, I would be curious to
know if you have any insight why these produce different results for the
same commands. I haven't tried out a load of different commands to see if
there is always discrepancy, but given my interest in dynamic panel data
modelling, I tried for example this and I get wildly different results:

xtabond y x1 x2 L.x3 , lags(1) pre(x4 x5 , lag(0,1))  twostep noconstant

Please try it out on your own data, using any variables for the y and the
x's, and see the different output. You don't have to know much about xtabond
to check whether the results are different (since they should not be). After
knowing what's going on here, the obvious next step is to find out which of
the two STata versions is "doing the right thing".
