Abstract

The logical operators & (“and”) and | (“or”) can sometimes be tricky in statistical software such as Stata. They are extremely useful, so you need to understand thoroughly how they work. Any trickiness arises mostly in translating from ordinary language to a statistical computer language. Here I survey various common confusions and explain what to do instead.
