st: xtabond2 : unable to allocate real / matrix has missing values, errors

[wojciechhardy <wojciechhardy@o2.pl>]

Hello,
I have encountered a problem while trying to make use of the xtabond2 function. Unfortunately this type of research is new to me and I'm afraid I need some guidance.

I get an error, specifically:
"                     J():  3900  unable to allocate real <tmp>[13664,11346]
         _MakeGMMinsts():     -  function returned error
         xtabond2_mata():     -  function returned error
                 <istmt>:     -  function returned error"
when trying to run the procedure. Adding a 'nomata' option (though I'm not sure if I should really use it) results in:
"matrix has missing values"

This is the code I use:
xtabond2 l_gdppc l5.n52 l5.n96 l5.yr_sch ki, gmm(l5.l_gdppc l5.n51) iv(le_rate l5.yr_sch ki openc) nomata

I'd appreciate any support you could give me. If it's any help, I could upload the dataset and describe the data in more detail.

Best regards,
Magdalena
