st: error r(7) from outreg

["roy wada" <roywada@hotmail.com>]

Nirina wants outreg to work with ivreg2. Her codes does not work
because ivreg2 does not always return a number in its scalars. In
other words, e(cdchi2) is probably missing from her regression result.

The following codes will work.

sysuse auto,clear
ivreg2 mpg price (headroom=rep78)
outreg using ivjune22,  br addstat(F-stat, e(F), sargan, e(sargan))

The following code will not work because some of the scalars are
missing from ivreg2 scalars.

outreg using ivjune22,  br addstat(F-stat, e(F), cragg, e(cdchi2), craggp, 
e(cdchi2p), craggF, e(cdf), sargan, e(sargan), sarganp, e(sarganp))

To see what is contained or missing from ivreg2 scalars, type these:

ssc install outreg2, replace
outreg2 using ivjune22,  br e(all) seeout

Her new codes would look like this:

outreg2 using ivjune22,  br addstat(F-stat, e(F), cragg, e(cdchi2), craggp, 
e(cdchi2p), craggF, e(cdf), sargan, e(sargan), sarganp, e(sarganp))
seeout
