How to merge 3 dummy variables

[GonzaloMR]

Hi there, I am currently working on panel data with 12 different panels. I have 3 independent dummy variables, which show a 1 if there is a rating upgrade for a bond, and a 0 if there is no announcement. Each dummy is for a different credit rating agency. How can I merge these dummies so that I have a fourth dummy variable made up of these 3?

thank you in advance for your help

How are you planning on defining the dummy? If any of the ratings is 1? If all?

Hi, i was thinking if any of the 3 has a one, that shows in the merged one. is that possible? thanks

Code: Select all

series dummyAll = dummy1 or dummy 2 or dummy3
