Random sample

[Patrick Turcotte]

Hello to all, I try to learn stata by myself as a economist,

So I want to make a boucle to make a random sample

I want to draw 500 samples of 1000 obs, from 10000 obs

Also in this boucle, if possible, i want to create variable like
x1 -> x1_mean , x2-> x2_mean etc...

Thank to help me, I did'nt put the code because is not working

I try that

forvalue j = 1/5{
generate x`j'_mean = .
}
//

forvalue i = 1/500{
sum x1 if runiform()<(0.1)
replace x1_mean = r(mean) in `i'
sum x2 if runiform()<(0.1)
replace x2_mean = r(mean) in `i'
sum x3 if runiform()<(0.1)
replace x3_mean = r(mean) in `i'
sum x4 if runiform()<(0.1)
replace x4_mean = r(mean) in `i'
sum x5 if runiform()<(0.1)
replace x5_mean = r(mean) in `i'
}

It's working, but do you thing I can reduce or simplified my loops?

Thank

Please read loops and not boucle...

French word for loops ;-)

Looks like variation on the bootstrap to me. Maybe the bootstrap prefix, the bsample command, or the vce(bootstrap) option helps.

Thanks , I will try that
