Daniel,

Thanks for pointing to this problem, I tried the same for Stata version 10 and got the error you're getting.


issue is that in Stata 9 (as well as in the previous versions) it was perfectly ok to have "/" symbol in the matrix rowname:

.matrix A = 4
.matrix rownames A = equation:/name

.matrix list A

symmetric A[1,1]
c1
equation:/name 4

if I write exactly the same in Stata 10:

.matrix rownames A = equation:/name
/name invalid name
r(198);

and this error persists even if I set version to 9 or 8

Can anybody suggest what might be the solution here?

thanks,
Zurab

Hi Zurab,

Thanks for your help. I have the same xml_tab version. However, when I
run your program it still generates an error:

/ln_sig invalid name
r(198);

I noticed that the ado was written for version 8. My version is 10. So I
tried

vers 8: xml_tab, replace save(c:\test)

, which most times generated the same error message. Sometimes it worked
but I could not infer the reason for that. The version command works
strange...

Hi Daniel,

I have -xml_tab- version 3.35 17Oct2007 available from SSC
and just tried following:

sysuse auto, clear
stset length
streg price rep78 trunk turn, distribution(gamma)

xml_tab, replace save(c:\test)

it worked.

Could you give me the full command line you use?  if you have the same
version but still get an error, there might be a case that it happens
only for specific combination of options.

Best,
Zurab

Hi,

I really like xml_tab which is a usefull tool to export tables of
estimates directly to Excel. However when I estimate a survival model
with streg and weibull distribution I get the following error message.

/ln_p invalid name
r(198)

This is not the case when I assume an exponential distribution since in
that case the parameter "p" (or ln_p) is not estimated. I guess xml_tab
has a problem with the "/". estout works fine but I would more like to
further use xml_tab.

Does anyone know a workaround? Thanks in advance.

-Daniel
