Hello, I was trying to use the twostepweakiv command to compute the AR 95% confidence intervals. The problem is that this command saves the interval as a string, so I cannot format the number of decimals included in the interval.
The example below generates the table that I am trying to compute, except, it includes too many decimals for the confidence intervals. Any ideas of how to reduced the size? Alternatively, has anyone else found any ways of
exporting the output of twostepweakiv into latex tables?


use http://www.stata.com/data/jwooldridge/eacsap/mroz.dta
generate byte poshours=(hours>0)

eststo clear
twostepweakiv 2sls lwage exper expersq (educ = fatheduc motheduc)
local ar = e(ar_cset)
local wald = e(wald_cset)
eststo:ivregress 2sls lwage exper expersq (educ = fatheduc motheduc)

estadd local arval "`ar'"
estadd local waldval "`wald'"
esttab using table.tex, se se(2) b(2) stats(arval waldval N, fmt(%15s %15s %12.0fc) labels("Schooling 95\% CI -- AR" "Schooling 95\% CI -- Wald" "N. of observations")) star(* 0.10 ** 0.05 *** 0.01) label nomtitles replace nogaps nonotes nonumber substitute(\_ _)
