Dear Stata list,
I was able to find a solution for my problem.
I used -gen idmatch = real(subinstr(hhid, " ", "", .))-
Please ignore the message.
Sincerely,
Gauri

Subject: st: destring id - for attnd matching in pscore

Dear Statalist,
I am using -pscore- module to conduct matching using the nearest neighbour
match with -attnd-. I would like to do some post-matching analysis and
would like to restrict my data to the matched group. I looked up -help
attnd- and ran the following command.
-attnd h11 wellsan v012 sexhhead v119 v136 v152 aware v730 v705 ///
rooms1to3 rooms4to5 propadult propwomen propmen v715 ///
v717 v714 v136v119 v715aware sh42 sh43 sh46 sh42sexhh ///
v730v119, pscore(pscorewellsan) comsup matchvar(scorewellsan)
matchdta(scorewellsan) id(hhid) boot reps(50) dots logit-
1. However, when I look at my data, I have all mising values for my id
variable "hhid". hhid = household id, is a string variable and which I have
used in the command above so that I can subsequently use this identifier to
merge with my original dataset and conduct the post-matching analysis. I
have listed "hhid" below so you can see what it looks like.
So I tried to destring my "hhid" variable but it gave the following error
- destring hhid, gen(IDmatch)-
hhid contains non-numeric characters; no generate
Then I used the -ignore- and -force- option but I got all missing values
for "hhid". How can I convert it to a numeric value so that I can use it
with -attnd-?
I will be grateful for your advice.
Sincerely,
Gauri
