Hi everyone,

I have two dummy variables, holder67 and holder30, which are equal to 1 if the value of another variable, COND is equal or above 0.67 and 0.30 respectively.

Now I am looking to generate a new dummy variable "holder30-holder67", which will equal to 1 if holder30=1 but holder67=0 to capture low-to-moderate degree of overconfidence.

What would be the code to generate such dummy variable dependent on the values of other dummy variables?

Thanks in advance!
