2.Mergeis for adding new variables from a second dataset to existing observations. You use merge, for instance, when combining hospital patient and discharge datasets. If you wish to add new observations to exi

By default, defv uses the same naming system as Stata's note command, so that the definitions it stores appear to have been created with note. (see [R] notes.) An advantage of this style is that variable definitions will be treated in the same way as other notes; for example, they ...

As computer capabilities have grown, so have dataset sizes. With larger datasets and more computationally intensive methods comes the above request, “Give me more speed.” Sometimes, our developers say, “I’m giving her all she’s got, Captain!”, but for Stata 17, they gave us all more...
