loops

[Benedicte Droz]

Hi!

I would like to create one single loop for these 3 sections... is that possible?
Many thanks!


gen lbWTP_ph = - AO_ph
replace lbWTP_ph = 75 if AO_ph == -76
replace lbWTP_ph = -1000 if AO_ph == 76

gen lbWTP_pa = - AO_pa
replace lbWTP_pa = 75 if AO_pa == -76
replace lbWTP_pa = -1000 if AO_pa == 76

gen lbWTP_pe = - AO_pe
replace lbWTP_pe = 75 if AO_pe == -76
replace lbWTP_pe = -1000 if AO_pe == 76


As well as a second loop for these 3 sections:


gen info_avoiding_ba = .
replace info_avoiding_ba = 1 if WTP_ba < 0
replace info_avoiding_ba = 0 if WTP_ba >= 0

gen info_avoiding_be = .
replace info_avoiding_be = 1 if WTP_be < 0
replace info_avoiding_be = 0 if WTP_be >= 0

gen info_avoiding_bh = .
replace info_avoiding_bh = 1 if WTP_bh < 0
replace info_avoiding_bh = 0 if WTP_bh >= 0

Is that possible?

Compare your question at https://stackoverflow.com/questions/...loops-in-stata

It's not the same question, but some of the ideas carry over.

Thank you very much! Yes, indeed. I was thinking about running the code below (inspired by your link) but it does not work.
gen lbWTP_ph = - AO_ph
gen lbWTP_pa = - AO_pa
gen lbWTP_pe = - AO_pe
gen lbWTP_ba = - AO_ba
gen lbWTP_be = - AO_be
gen lbWTP_bh = - AO_bh

foreach v in lbWTP_ph lbWTP_pa lbWTP_pe lbWTP_bh lbWTP_ba lbWTP_be {
replace `v' = 75 if `-v' == -76
replace `v' = -1000 if `-v' == 76
}

Thank you!

You have an extra - in `v'. On the other hand, it might be easy to understand to iterate through ph pa pe

foreach v in ph pa pe bh ba be {
    replace lbWTP_`v' = 75 if AO_`v' == -76
    replace lbWTP_`v' = -1000 if AO_`v' == 76
}
