Hi all,

I tested my model again and found out that the problem is caused by .outreg.
The code does some things strange with dynamic panel data model.

Thanks,

Thuy Le

Subject: st: xtabond deletes some variables


Hi all,

Does anyone experience the problems with .xtabond command that deletes some
variables after the estimation?

This is my command:
	. xtabond goldcap inflation gdpcapgro real loggdpcap95 sdevgdp
sdevinflation loggoldlcu credgdp stkpen, lags(1) artests(2)

The results come out OK, but when I run .outreg
	. outreg using august2a.out

STATA gives the following error:
	"variable goldcap not found"

When I rerun the .xtabond command above, STATA produces the same error
message:
	"variable goldcap not found"

When I check the variables window, the variable named "goldcap" is not
there.

(The version of STATA is 8.2)

Thank you for your help,

Thuy Le

This depends on what you are looking for and what the data
are like. Note that the display format of the numeric
variable you are trying to convert is
irrelevant unless you use the -usedisplayformat-
option.

The most relevant part of the help is probably
this:

-force- specifies that conversions entailing loss
of information may be forced.  Loss of
information means one of two circumstances:  (1) The result of
real(string(varname,
"format")) is not equal to varname, i.e. the conversion is not reversible
without
loss of information.  (2) replace was specified but a variable has
associated value
labels.  In circumstance (1), it is usually best to specify usedisplayformat
or
format().  In circumstance (2), value labels will be ignored in a forced
conversion.  Note also decode as the standard way to generate a string
variable
based on value labels.
