Mark,

You cannot use -outreg-, -outreg2-, or -estout- to format the statistics from -corrgram- directly, because it is not an estimation command.  In particular, it does not save results in the e(b) matrix.  Instead it saves results in r() matrices.

You can create a formatted table of -corrgram- statistics with the following commands using the program -frmttable-, which is the backend of -outreg-.  It takes a Stata matrix and creates a formatted table in Word or TeX.

webuse air2, clear
corrgram air, lags(20)
mat lags = J(r(lags),1,0)
mat probQ = lags
mat Q = r(Q)'

forvalues r=1/`r(lags)' {
	mat lags[`r',1] = `r'
	mat probQ[`r',1] = chi2tail(`r',Q[`r',1])
}
mat stat = lags,r(AC)',r(PAC)',Q,probQ
frmttable using corrgram.doc, statmat(stat) ctitle("Lag","AC","PAC","Q","Prob>Q") ///
	sdec(0,4) replace

The reason for the matrix commands above is to calculate the "Prob>Q" p-values which are not saved in r() values after the -corrgram- command.

The -frmttable- command is part of the -outreg- package, which you can download with the command -ssc install outreg, replace-.  Find more information in -help frmttable- after you download it.
