Ever needed to do a similar factor to ten various variables and wished which you didn't have to write down it out 10 periods? If that is so, then this text is for you. Otherwise, sometime you'll—so you might likewise Continue reading anyway.

A variable name is usually abbreviated to your minimal amount of letters which makes it special in a very dataset. For example inside our fast tour we could check with loggnppc as log as it is the only variable that starts with People 3 letters, but that is a actually terrible strategy.
