Hi,
I'm trying to create a dummy variable that takes on a value of 1 if another (continuous) variable (=PSLIQ) is higher than 2 times its corresponding standard deviation and takes on a value of 0 otherwise.
The variable that I am looking at is "PSLIQ" in my dataset and it has a standard deviation of around 0.033.
I've already tried doing:
egen stdev = sd(PSLIQ)
but that is where I get stuck. Hopefully someone can help, thanks!
Here is an example of my dataset:
