Subject: st: Generate Variable
Hi Statalisters,
I have a quick question. I am trying to create a dummy
variable that is equal to 1 when organizations have more
properties in wave 6 compared to wave 4. My data is in long
form.
Logically, it would be something like this, but this does not
work, I am missing some steps.
gen HiPropertyw6= 1 if (numProp==wavenum==4 <
numInsArrng==wavenum==6).
