I've just done the update.

I dont understand why 3 other error messages appear after the GMM command:

xtabond2 y a b c axb axc, gmm (y b c, eq(diff)) iv (a, eq(level)) two
robust small

estimates post: matrix has missing values
                 stata():  3598  Stata returned error
         xtabond2_mata():     -  function returned error
                 <istmt>:     -  function returned error
r(3598);

xtabond2 y a b c axb axc, gmm (y b c, eq(diff)) iv (a, eq(level)) two
robust small

It syas that matrix has missing values?
I'm using longitude panel data, so I wonder if there's anything on the
format of my data I need to set up first that I haven't?
