Hi everyone,

I am running a difference in differences regression with Panel data on Stata version 14.2.

I have state-level clustered standard errors, but since there are only 32 states in my data I want to use bootstrapping to correct for bias in the standard errors.

Since I am using survey data I need to include weights [pweight]. These are, however, incompatible with the bootstraps option after reg.

I was recommended the

I run the following code:

I get the following error message after the line
:

.

Any idea how to fix this?

Any help is greatly appreciated.

I am running a difference in differences regression with Panel data on Stata version 14.2.

I have state-level clustered standard errors, but since there are only 32 states in my data I want to use bootstrapping to correct for bias in the standard errors.

Since I am using survey data I need to include weights [pweight]. These are, however, incompatible with the bootstraps option after reg.

I was recommended the

**boottest**command, but I have trouble getting the results out of Stata into a table.I run the following code:

Code:

reg violence treat i.state i.year [pweight=factor] if year>2003, cluster(ent) matrix v = e(V) matrix b = e(b) boottest treat=0, boottype(wild) seed(22) matrix v[1,1] = (_b[treat]/r(t))^2 eststo: ereturn post b v sum violence if year>2003 local N = r(N) local mean = r(mean) estadd scalar m = `mean' estadd scalar obs = `N' #delimit ; esttab, b(%-9.3f) se(%-9.3f) noobs keep(treat) nonotes nogaps mlabels(, none) nonumbers style(tex) fragment replace noline label stats(obs m, fmt(%9.0gc %5.3f) label("\\ Observations" "Mean of Dependent Variable")); #delimit cr

I get the following error message after the line

Code:

eststo: ereturn post b v

last estimation results not found, nothing to store

r(301);

r(301);

Any idea how to fix this?

Any help is greatly appreciated.
